I supply 4-Isopropylbenzeneboronic acid, CAS 16152-51-5, as a specialty organic boronic acid for research, medicinal chemistry, and synthetic development. The compound is commonly selected as an aryl boronic acid building block for carbon–carbon bond-forming reactions, particularly Suzuki–Miyaura coupling, although the exact suitability depends on the reaction system and project requirements. Its molecular formula is generally represented as C9H13BO2, with a calculated molecular weight of approximately 164.01 g/mol. In this guide, I explain how buyers can evaluate identity, quality, packaging, documentation, lead time, and supplier capability before placing an order.
This guide is intended for procurement specialists, process chemists, medicinal chemistry teams, contract research organizations, and distributors sourcing 4-Isopropylbenzeneboronic acid. It is also useful for buyers moving from milligram-scale screening to gram-scale route development. Because boronic acids can be sensitive to handling, storage, and reaction conditions, purchasing decisions should consider more than the chemical name alone.
I recommend using this guide when you need a reliable source for a defined research grade, a repeat supply arrangement, or an initial quotation for custom packaging. It can also help buyers compare suppliers that list the same CAS number but provide different levels of analytical documentation and technical support. The final specification should always be confirmed against the intended reaction, regulatory environment, and internal quality system.
4-Isopropylbenzeneboronic acid is an aryl boronic acid containing a boronic acid functional group attached to a phenyl ring bearing an isopropyl substituent in the para position. The boronic acid group gives the molecule value as a reactive synthetic handle, while the isopropyl group contributes a hydrophobic and steric feature that can influence the behavior of a target molecule. The compound is generally used as an intermediate rather than as a final formulation ingredient.
For identity control, I advise buyers to verify the name, CAS number, molecular formula, molecular weight, structural representation, and analytical data together. CAS 16152-51-5 should be checked against the supplier’s certificate of analysis and product label. A single matching name is not sufficient if the project requires a defined isomer or a controlled impurity profile.
The principal procurement rationale is its potential use as an aryl coupling partner in synthetic chemistry. In a suitable palladium-catalyzed or related coupling system, an aryl boronic acid may react with an aryl or heteroaryl halide to form a biaryl structure. Actual conversion depends on catalyst selection, base, solvent, temperature, substrate compatibility, and reaction work-up, so I present this as a common synthetic application rather than a guaranteed performance claim.
Researchers may also evaluate this building block during analogue synthesis, structure–activity relationship programs, and route scouting. The para-isopropyl substitution can be useful when a project is studying the effect of a hydrophobic substituent on molecular properties. Whether it is the best choice should be determined through experimental screening and analytical confirmation.
Different suppliers may offer the same CAS number in different package sizes, purity grades, and documentation formats. Before comparing prices, I recommend creating a written purchase specification that identifies the required purity method, residual solvent expectations, water limits if relevant, appearance requirements, and documentation package. This avoids comparing products that are technically different even when their catalog descriptions appear similar.
| Procurement item | What to confirm |
|---|---|
| Identity | CAS 16152-51-5, chemical name, formula, molecular weight, and structure |
| Purity | Assay method, reporting basis, and specified minimum value |
| Impurities | Related substances, residual solvents, inorganic residues, and water where applicable |
| Documentation | Certificate of analysis, safety data sheet, batch information, and packing details |
| Supply format | Available quantity, container type, labeling, and shipment conditions |
A buyer may, for example, request an assay specification of not less than 98.0% by a defined analytical method, but that value must be agreed with the supplier and should not be assumed to describe every market offering. Similarly, the calculated molecular weight of approximately 164.01 g/mol is useful for material balance and solution preparation, but it does not replace identity testing. I recommend requesting a representative certificate of analysis before approving a new source.
For early-stage research, the most important factors are confirmed identity, usable purity, practical pack size, and rapid access to analytical documentation. A small quantity can support reaction screening, while a later campaign may require a larger batch from the same or a qualified manufacturing route. Buyers should keep the original batch number and retain sufficient material for comparison if the project is sensitive to lot-to-lot variation.

Process teams should evaluate more than reaction conversion. They may need information about impurity trends, assay reproducibility, residual solvents, moisture, filtration behavior, and the supplier’s ability to repeat the same specification. A supplier that can discuss scale, packaging, and batch consistency is generally more useful than a source that only provides a catalog price.
Distributors should confirm whether the material is available as a standard product, made to order, or sourced through a third party. They should also verify label language, safety documentation, country-of-origin information where required, and the ability to support repeat orders. I recommend avoiding any representation about shelf life, storage temperature, or regulatory status unless it is supported by the current product documentation.
I use a five-part framework when helping customers evaluate a supplier: identity, quality, capacity, logistics, and communication. Identity confirms that the offered material is the requested para-substituted compound. Quality addresses the agreed analytical specification and batch documents. Capacity covers whether the supplier can support the required quantity and future demand without changing the specification unexpectedly.
Lead time and MOQ should be treated as quotation-specific rather than universal product facts. A laboratory pack, pilot quantity, and manufacturing quantity may have different pricing and preparation requirements. When requesting a quote, I suggest specifying the target quantity in grams or kilograms, required delivery destination, preferred pack configuration, and whether a pre-shipment document review is needed.
One common mistake is purchasing based only on the CAS number without checking the positional isomer and analytical method. Another is comparing a low unit price without accounting for packaging, documentation, freight, import requirements, and the cost of qualifying a replacement supplier. Buyers may also overlook whether the supplier can repeat the same product specification after the first order.
It is also risky to assume that every aryl boronic acid will behave identically in a coupling reaction. Boronic acid stability, substrate effects, catalyst choice, and work-up conditions can all affect experimental results. For important projects, I recommend a controlled comparison using a documented lot rather than changing supplier and reaction conditions at the same time.
At Maison Chemical, I support B2B buyers by focusing on clear product identification, practical quotation communication, and supply coordination for 4-Isopropylbenzeneboronic acid CAS 16152-51-5. I can help organize discussions around target quantity, purity requirement, packaging, documentation, destination, and delivery expectations. Where a customer has a project-specific specification, I recommend reviewing the requirement before confirming the commercial offer.
Our role is not limited to listing a chemical name. We aim to help buyers establish whether the requested material is suitable for their procurement stage, from initial research screening to repeat laboratory supply or broader route-development planning. Availability, MOQ, lead time, and final pricing should be confirmed for each order because they may vary with quantity, batch status, packaging, and destination.
