For procurement managers and R&D scientists in the chemical and pharmaceutical sectors, sourcing high-quality raw materials is paramount. 4-Aminobenzoic Acid (PABA), CAS 150-13-0, stands out as a critical intermediate with diverse applications ranging from pharmaceuticals to cosmetics. Understanding its properties, applications, and the nuances of procurement can significantly impact product development and cost-efficiency. As a leading manufacturer and supplier in China, we aim to demystify the process of acquiring this vital compound.

Understanding 4-Aminobenzoic Acid (PABA)

4-Aminobenzoic Acid is an organic compound with the molecular formula C7H7NO2. It typically appears as a white crystalline powder and is known for its utility across several industries. Its key applications include:

• Pharmaceutical Intermediates: PABA serves as a foundational building block in the synthesis of various active pharmaceutical ingredients (APIs). It is instrumental in creating local anesthetics like procaine and tetracaine, as well as in the production of certain dyes and antifibrotic agents. For companies developing new drugs or manufacturing established pharmaceuticals, a reliable supply of high-purity PABA is essential.
• Cosmetics and Sunscreens: Historically, PABA was a prominent ingredient in sunscreens due to its effective absorption of UVB radiation. While newer compounds have emerged, PABA derivatives are still utilized in some cosmetic products. Its UV-filtering properties make it valuable for personal care product formulations.
• Biochemical Applications: In the field of biochemistry, PABA plays a role in the synthesis of folate by certain bacteria. This makes it a compound of interest in microbiological research and studies related to bacterial metabolism.

Key Considerations for Buyers

When looking to buy 4-Aminobenzoic Acid, several factors should be at the forefront of your decision-making process:

• Purity and Specifications: For pharmaceutical applications, a high assay (typically ≥99.0%) is non-negotiable. Buyers should carefully review product specifications, including melting point (186-189°C), solubility, and impurity profiles. Ensuring compliance with USP or EP standards may be necessary for certain uses.
• Supplier Reliability: Establishing a relationship with a reputable 4-Aminobenzoic Acid supplier is critical for consistent quality and timely delivery. Look for manufacturers with robust quality management systems, clear documentation (like Certificates of Analysis - COA), and a proven track record.
• Price and Value: While cost is always a factor, it should be balanced against quality and reliability. Requesting a quote for 4-Aminobenzoic Acid from multiple suppliers, including those based in China, can help secure competitive pricing without compromising on essential product attributes.
• Regulatory Compliance: Depending on your market and application, ensure the PABA you purchase meets all relevant regulatory requirements.
