Description

Butyl 4-Aminobenzoate (CAS NO 94-25-7) is an ester derivative of para-aminobenzoic acid (PABA), valued for its UV-absorbing properties and role as a versatile chemical intermediate. This compound is essential for formulators and manufacturers requiring a specific lipophilic benzocaine analog or a UV filter precursor. It is primarily sought by the pharmaceutical, personal care, and specialty chemical industries for applications ranging from topical anesthetics to sunscreen actives.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of ester-type local anesthetics, such as benzocaine derivatives.
• UV Filter / Sunscreen Agent: Used as an active ingredient or a starting material for formulating UV-absorbing compounds in sun care products.
• Chemical Synthesis: Serves as a building block for organic synthesis, particularly in creating more complex PABA esters and amides.
• Cosmetic Additive: Employed in cosmetic formulations for its functional properties, contributing to product stability and performance.
• Research & Development: Utilized in laboratory settings for biochemical research and the development of new pharmaceutical compounds.
• Industrial Applications: Potential use in polymer stabilizers or as an additive in coatings where UV protection is required.
