For any professional in the chemical or pharmaceutical industry, understanding the detailed specifications of a raw material is the first step towards ensuring successful application and reliable results. 1-(3-Chlorophenyl)cyclopropanecarboxylic acid (CAS: 124276-34-2) is a prime example of a pharmaceutical intermediate where precise specifications are paramount. This article outlines the key technical details that procurement managers and R&D scientists should be aware of when looking to buy this compound.

At the core of any chemical specification is its identity and purity. For 1-(3-Chlorophenyl)cyclopropanecarboxylic acid, the CAS number 124276-34-2 serves as a unique identifier, distinguishing it from other chemical entities. The molecular formula, C10H9ClO2, and the corresponding molecular weight of 196.63 g/mol provide fundamental information about its elemental composition and mass. These are baseline parameters that confirm the identity of the substance.

However, for its intended use as a pharmaceutical intermediate, the purity level is of utmost importance. Reputable manufacturers and suppliers will typically offer this compound with a minimum purity of 99%. This high level of purity is critical to prevent unwanted side reactions, ensure the efficacy of downstream synthesis, and meet the stringent regulatory requirements of the pharmaceutical sector. When evaluating a supplier, verifying their quality control procedures and the availability of certificates of analysis (CoA) that confirm this purity is essential.

Beyond purity, other specifications can influence the suitability of the material for specific applications. While the provided source material does not detail physical form or precise melting/boiling points for this specific compound, these are common parameters to inquire about. For instance, understanding if it is a solid or liquid at room temperature can impact handling and storage protocols. The source of the material, whether it is synthesized by a dedicated manufacturer in China or elsewhere, can also be a factor, influencing lead times and logistical considerations for worldwide delivery.

When considering the price of 1-(3-Chlorophenyl)cyclopropanecarboxylic acid, it's crucial to compare not just the cost per kilogram but also the assurance of meeting these critical specifications. A slightly higher price from a trusted supplier that guarantees 99% purity is often more economical in the long run than a cheaper alternative that may contain impurities, leading to failed syntheses or costly purification steps. Therefore, a thorough review of product specifications should always be the first step before making a purchase.
