In the realm of chemical manufacturing, identifying and securing reliable sources for versatile intermediates is key to driving innovation and ensuring product quality. 4-Aminobenzoic acid, commonly known as PABA and bearing the CAS number 150-13-0, is a prime example of such an essential compound. Its unique molecular structure and reactivity make it a cornerstone in several industrial applications, most notably in the production of dyes and pharmaceuticals. As a dedicated manufacturer and supplier, we offer high-purity PABA to meet the rigorous demands of modern chemical enterprises.

The Chemical Profile of 4-Aminobenzoic Acid

4-Aminobenzoic acid presents itself as a white crystalline powder, typically with an assay of 99% or higher. This purity is critical for its function as a building block in complex chemical syntheses. The molecule's structure, comprising a para-substituted benzene ring with an amino (-NH2) and a carboxyl (-COOH) group, dictates its chemical behavior and utility:

  • Reactivity: The amino group can be easily diazotized, a crucial step in forming azo dyes. The carboxyl group allows for esterification and amide formation, expanding its use in various organic syntheses.
  • UV Absorption: PABA is known to absorb ultraviolet radiation, a property that historically led to its use in sunscreen formulations.
  • Biological Relevance: It's a precursor in the synthesis of folic acid in many bacteria and plants, although it is not considered an essential vitamin for humans.

Key Industrial Applications

The demand for 4-Aminobenzoic acid is driven by its critical role in several key industries:

1. Dye Manufacturing: PABA is a foundational intermediate for producing a wide range of azo dyes. These dyes are vital for coloring textiles, leather, paper, and plastics. Companies looking to buy PABA for dye synthesis benefit from its predictable reactivity and the resulting brilliant colors it helps create. Our commitment to providing high-purity PABA ensures consistency in your colorant production.

2. Pharmaceutical Synthesis: In the pharmaceutical sector, PABA serves as a precursor for synthesizing various active pharmaceutical ingredients (APIs) and their intermediates. For example, it is used to produce compounds like p-carboxybenzylamine. The stringent quality requirements of pharmaceutical manufacturing necessitate a reliable supply of intermediates like PABA. For procurement managers, sourcing from a reputable manufacturer like us guarantees the quality needed for drug development and production.

3. Cosmetic and Personal Care: While less common now, PABA's UV-absorbing properties have led to its inclusion in some cosmetic products and older sunscreen formulations. Understanding these historical applications can inform modern product development. If your company is investigating ingredients for UV protection, consider PABA as a potential component.

4. Nutritional Supplements: Though not an essential vitamin for humans, PABA is involved in biochemical pathways and is used in the synthesis of certain nutritional compounds. Sourcing PABA for these applications requires a supplier who can guarantee consistent quality and supply.
