4-Cyanobenzoic acid (CAS 619-65-8) is a chemical compound characterized by its off-white powder appearance and a melting point typically ranging between 219-224 °C. This white to yellow-beige crystalline powder is relatively stable but sensitive to air and incompatible with strong oxidizing agents, strong acids, and strong bases. Proper understanding and adherence to its properties are vital for effective utilization in various synthesis processes.

The compound is soluble in methanol and has limited solubility in water (approximately 1.2 g/L at 20°C). Its stability under recommended storage conditions – typically in a dry, cool place, often under an inert gas – ensures its integrity for laboratory and industrial use. When handling this chemical intermediate, it is important to be aware of its hazard statements, which often include warnings for skin irritation, serious eye irritation, and potential respiratory irritation. Appropriate personal protective equipment (PPE) should always be used.

For researchers and manufacturers, sourcing reliable information on '4-cyanobenzoic acid properties' and '4-cyanobenzoic acid MSDS' is a prerequisite for safe and efficient handling. The availability of Safety Data Sheets (SDS) and Product Specifications (PS) from suppliers like NINGBO INNO PHARMCHEM CO., LTD. provides essential details on safe handling, storage, and disposal procedures. This ensures that the compound maintains its quality and that operations involving it are conducted with the utmost safety.

By understanding these critical properties, users can better integrate 4-cyanobenzoic acid into their research and production workflows, ensuring successful outcomes and minimizing risks associated with its handling and storage. Accessing detailed product specifications is key for anyone looking to 'buy 4-cyanobenzoic acid' for their specific applications.
