The Chemical Profile of PABA: Properties, Specifications, and Applications
Para-Aminobenzoic Acid (PABA), identified by its CAS number 150-13-0 and molecular formula C7H7NO2, is a significant organic compound with a distinct chemical profile that dictates its wide-ranging applications. Typically appearing as a white crystalline powder, PABA exhibits solubility in various organic solvents, including hot water, ethyl ether, and ethanol, while being insoluble in water and petroleum ether. This solubility characteristic is crucial for its effective use in different chemical processes.
The specifications for PABA are often delineated into industrial and pharmaceutical grades, each tailored to meet specific industry requirements. Industrial grade PABA generally boasts an assay of 99.0% minimum, suitable for applications like dye synthesis. Pharmaceutical grade PABA adheres to even more rigorous standards, with an assay ranging from 98.5% to 101.5%, and stricter limits on impurities like loss on drying, volatile diazoizable substances, residue on ignition, and heavy metals. These high standards ensure the safety and efficacy required for pharmaceutical intermediates and other sensitive applications.
The applications of PABA are diverse. It is a key intermediate in the production of various dyes, contributing to color formulation in the textile and printing industries. Furthermore, it serves as a crucial intermediate in pharmaceutical synthesis, enabling the creation of essential drug compounds. Historically, PABA was also utilized as a sunscreen agent due to its UV-blocking properties, although its use in this capacity has evolved.
For businesses looking to procure PABA, understanding these specifications and applications is vital. Sourcing from reputable manufacturers, such as those in China, who can provide detailed technical data sheets (TDS) and Certificates of Analysis (COA) is recommended. The typical packaging of 25kg/fiber drums and the availability for purchase with a minimum order of 1kg make it accessible for various operational scales. Whether you are looking to buy PABA for dye production, pharmaceutical development, or other chemical processes, ensuring you obtain the correct grade and purity is paramount for successful outcomes.
