In the complex world of pharmaceutical manufacturing, the quality and purity of raw materials are paramount. 4-Aminobenzoic Acid, commonly known as PABA (CAS 150-13-0), stands out as a critical intermediate with diverse applications, particularly in the synthesis of essential drugs. For any pharmaceutical company looking to secure a reliable supply, understanding the nuances of sourcing high-purity PABA from reputable manufacturers and suppliers is key.

PABA is an organic compound with the molecular formula C7H7NO2. It typically appears as a white crystalline powder and is known for its significant role in the production of various pharmaceuticals. One of its most prominent uses is as a precursor in the synthesis of local anesthetics, such as procaine and tetracaine. These anesthetics are vital in medical procedures, and their efficacy is directly linked to the quality of the PABA used in their production. Furthermore, PABA is an indispensable component in the biosynthesis pathway of folic acid (Vitamin B9) in bacteria and plants, though humans obtain folate from dietary sources or supplements. This biochemical role underscores its importance in research and development within the life sciences sector.

Beyond pharmaceuticals, PABA has historically found a place in the cosmetic industry as a UVB absorber, a component in early sunscreen formulations. While newer sunscreens utilize different active ingredients, its role in historical formulations and potential in specialized cosmetic applications remains relevant for some manufacturers. The compound is also employed in the dye industry as an intermediate, contributing to the creation of specific azo dyes. This highlights PABA's versatility as a chemical building block.

When considering the purchase of 4-Aminobenzoic Acid, several factors are crucial for B2B buyers. The assay purity is a primary concern, with specifications often demanding 99% or higher. Suppliers adhering to USP, BP, EP, and FCC standards provide assurance for pharmaceutical-grade materials. Buyers are actively searching for 'buy 4-aminobenzoic acid CAS 150-13-0 supplier' or 'PABA manufacturer in China' to identify reliable sources. The price of PABA is also a significant consideration, especially for bulk orders, making direct inquiries to manufacturers for quotes essential.

For companies in need of this chemical intermediate, partnering with a reputable manufacturer offers significant advantages. These include consistent quality control, adherence to international standards, and competitive pricing, especially when purchasing in larger quantities. Engaging with suppliers who can provide Certificates of Analysis (COA) and support R&D purposes further solidifies the procurement process. Ultimately, securing a dependable supply of high-purity 4-Aminobenzoic Acid is fundamental to ensuring the quality and integrity of downstream products in the pharmaceutical, cosmetic, and chemical industries.
