Description

4-Aminobenzoic Acid Sodium Salt is the water-soluble sodium salt form of para-aminobenzoic acid (PABA), a key organic compound. This form offers enhanced stability and solubility, making it a crucial intermediate and active ingredient in advanced chemical synthesis. It is primarily utilized by the pharmaceutical, cosmetic, and fine chemical industries for applications requiring a bioavailable source of PABA.

Application

• Pharmaceutical Intermediate: Used in the synthesis of folic acid analogs, local anesthetics (e.g., procaine), and other active pharmaceutical ingredients (APIs).
• UV Protection & Cosmetics: Serves as a raw material in sunscreen formulations and skincare products due to its ability to absorb ultraviolet (UV) light.
• Biochemical Research: Employed as a vital nutrient and growth factor in microbiological culture media and biochemical studies.
• Dye & Pigment Synthesis: Acts as a precursor in the production of azo dyes and other organic colorants.
• Food & Feed Supplement: Used as a vitamin source (Vitamin Bx) in niche nutritional fortification applications.
• Industrial Chemical Synthesis: Functions as a versatile building block for organic synthesis, including the manufacture of polymers and specialty chemicals.
