Description

p-Aminobenzoic Acid Potassium Salt is the potassium salt derivative of para-aminobenzoic acid (PABA), a key organic compound. This salt form offers enhanced solubility and stability, making it a valuable intermediate for synthesis and formulation. It is primarily utilized in the pharmaceutical, research, and fine chemical industries for applications requiring a bioavailable source of PABA.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of folic acid analogs, local anesthetics (e.g., procaine), and other active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a precursor or substrate in enzymatic studies and microbiological assays, particularly in folate pathway research.
• UV-Absorbing Agent: Incorporated into specific sunscreen formulations and cosmetic products for its ultraviolet light filtering properties.
• Nutritional Supplement Precursor: Serves as a source material for the production of PABA, which is used in certain vitamin B-complex supplements.
• Organic Synthesis: Employed as a reagent in various organic reactions, including diazotization and the preparation of azo dyes.
• Laboratory Reagent: Used as a standard or analytical reagent in quality control and research laboratories.
