Description

4-Aminobenzoic Acid Isobutyl Ester is an organic chemical ester derivative of para-aminobenzoic acid (PABA). This compound is valued for its role as a versatile chemical intermediate and UV-absorbing functional group in advanced material synthesis. It is primarily sought by manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries for research and production applications.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring UV-protective or lipophilic properties.
• Sunscreen & Cosmetic Formulations: Acts as an organic UV filter (UVB absorber) in sun care products, lotions, and protective creams.
• Polymer & Material Science: Serves as a monomer or additive in the production of specialty polymers, coatings, and resins designed for enhanced light stability.
• Organic Synthesis Building Block: Utilized in research and development for constructing more complex molecules, including dyes and agrochemicals.
• Laboratory Reagent: Employed as a standard or reagent in analytical chemistry and biochemical research.
