In the complex landscape of pharmaceutical development, the quality and availability of intermediate compounds are paramount. 4-Methoxybenzoic Acid, identified by its CAS number 100-09-4 and commonly known as p-Anisic Acid, stands out as a fundamental building block. This white crystalline solid is indispensable for the synthesis of a wide range of active pharmaceutical ingredients (APIs), making it a compound of significant interest to the pharmaceutical industry.

The chemical structure of 4-Methoxybenzoic Acid, CH3OC6H4COOH, with a molecular weight of 152.15 g/mol, provides a versatile scaffold for medicinal chemists. Its well-defined physical properties, including a melting point between 182-186°C and solubility in organic solvents, facilitate its use in various synthetic reactions. The importance of sourcing high-purity material cannot be overstated, as impurities can significantly impact the efficacy and safety of the final drug product. Therefore, manufacturers specializing in 4-Methoxybenzoic acid CAS 100-09-4 synthesis often adhere to stringent quality control measures.

When seeking to buy 4-Methoxybenzoic acid online for pharmaceutical applications, buyers must prioritize suppliers with a proven track record of quality and consistency. This includes reviewing Certificates of Analysis (CoA) and ensuring compliance with relevant industry standards. The p-anisic acid price can vary based on purity, order volume, and supplier location, making it essential to compare offers from multiple sources. Companies from China are often notable for their competitive pricing due to large-scale production.

Identifying reliable 4-Methoxybenzoic acid suppliers is crucial for maintaining a stable supply chain for pharmaceutical intermediates. These suppliers not only provide the chemical but also offer technical support and ensure timely delivery. Understanding the specific requirements of pharmaceutical synthesis—such as required purity levels, particle size, and residual solvent limits—allows buyers to effectively communicate their needs to potential vendors.

In conclusion, 4-Methoxybenzoic Acid (CAS 100-09-4) is a critical component in the pharmaceutical manufacturing pipeline. Its role as a versatile intermediate underscores the need for careful sourcing, prioritizing purity, reliability, and competitive pricing from trusted manufacturers. By focusing on these aspects, pharmaceutical companies can ensure the consistent availability of this vital building block, thereby supporting the development and production of essential medicines.
