4-Propylphenylboronic acid (CAS 134150-01-9) is an arylboronic acid used as an organic building block, particularly in palladium-catalyzed Suzuki–Miyaura cross-coupling. Its aryl group can be coupled with a suitable aryl or vinyl halide to form a carbon–carbon bond, while the para-propyl substituent remains part of the product structure. The compound has the molecular formula C9H13BO2 and a calculated molar mass of 164.01 g/mol. Buyers should confirm the required grade, analytical evidence, packaging, availability, and delivery terms with the supplier before ordering.
This guide is intended for procurement teams, process chemists, medicinal and materials chemistry groups, and distributors evaluating 4-Propylphenylboronic acid. It explains how to check product specifications and assess fit for a coupling route without assuming that every supplier offers the same grade or commercial terms. It is also useful when preparing a quotation request or comparing supplier responses. Final selection should be based on the buyer’s documented process and quality requirements.
4-Propylphenylboronic acid is an arylboronic acid: a phenyl ring bearing a boronic acid group and a propyl substituent at the para position. The CAS Registry Number supplied for this product is 134150-01-9. Its molecular formula is C9H13BO2, corresponding to a calculated molar mass of 164.01 g/mol.
The boronic acid functionality makes the molecule useful as a coupling reagent in appropriate reaction systems. During Suzuki–Miyaura coupling, an organoboron partner reacts with a suitable electrophile, commonly an aryl or vinyl halide, in the presence of a catalyst and base. The precise reaction outcome and performance depend on the other substrate, catalyst, base, solvent, and operating conditions, so the compound should be evaluated in the buyer’s own reaction design.
A product name and CAS number are a starting point, not a complete purchasing specification. Ask the supplier to confirm the material’s identity and the analytical methods used to support its stated assay. Confirm whether a reported purity is based on HPLC area percentage, weight percentage, or another method, because these values are not automatically interchangeable.
| Item to review | What to confirm | Why it matters |
|---|---|---|
| Identity | Product name, CAS number, formula, and supporting analytical data | Helps ensure the quoted material matches the intended chemical building block. |
| Assay or purity | Acceptance limit, analytical method, and reporting basis | Allows a meaningful comparison with internal project requirements. |
| Impurity and moisture information | Available results, limits, or specification status | May be relevant to reaction reproducibility, storage, or downstream quality controls. |
| Documents | Certificate of Analysis (CoA), Safety Data Sheet (SDS), and batch identification | Supports incoming-material review, handling, and traceability processes. |
| Packaging and storage | Pack size, closure, storage guidance, and transport conditions | Helps buyers plan receipt, storage, and use in line with supplier documentation. |
If your project requires a particular purity, state the target explicitly rather than treating an example value as a supplier guarantee. For instance, a buyer might request a target of 98% by a specified method, but this is a procurement requirement to confirm, not a claim about every available lot. Request batch-specific documentation when the material will enter a controlled development or manufacturing workflow. Where a critical impurity limit is needed, define it in the specification and confirm whether the supplier can report against it.
Consider 4-Propylphenylboronic acid when the target structure requires the para-propyl-substituted aryl group to be introduced through a carbon–carbon coupling step. The most direct fit is a route in which the desired product can be formed by coupling this boronic acid with a compatible aryl or vinyl electrophile. The boronic acid is a starting material, not a catalyst or a universal coupling solution.

Reaction development should account for the identity and reactivity of the coupling partner, catalyst system, base, solvent, and work-up. As an initial screening design, a chemist may test approximately 1.0–1.5 molar equivalents of the boronic acid relative to the limiting substrate; this is a planning range for experiments, not a guaranteed optimum. Screen conditions on an appropriate scale and assess conversion, selectivity, and product isolation using methods suitable for the project. Do not assume that one reaction recipe will transfer unchanged across different substrates or scales.
Compare other boronic acids, boronate esters, or alternative coupling strategies when the route’s selectivity, stability, solubility, or work-up requirements make the free boronic acid inconvenient. The right choice depends on the specific reaction sequence and on what forms of the reagent are available and qualified. Ask the chemist responsible for the route to define the functional and analytical requirements before procurement commits to a material. This avoids buying on name similarity alone.
Price, minimum order quantity (MOQ), and lead time can vary with requested quantity, grade, stock status, packaging, destination, and documentation requirements. These commercial details should be confirmed against a current quotation rather than inferred from a product name or an older offer. A small evaluation quantity may suit initial reaction screening, while scale-up planning may require a separate availability and quality review. When asking for a quote, provide a target quantity and required delivery location so the supplier can respond on a comparable basis.
For budget comparisons, distinguish the unit price from total delivered cost. Packaging, freight, import requirements, and any special documentation or specification work can affect the purchasing decision. If the schedule is critical, request an estimated dispatch or delivery window and clarify whether it depends on stock confirmation. Treat any estimate as subject to the supplier’s written confirmation.
