This aromatic amino ester with tertiary dibutylamino side chain is a specialized fine chemical intermediate mainly used in cosmetic UV-absorber synthesis, dye intermediate and pharmaceutical research development. The free para-amino group on benzoate ring enables diazotization and coupling reactions for manufacturing azo dyes and optical brighteners. Its long alkyl tertiary amine structure brings excellent lipophilicity and moderate water dispersibility, making it an important precursor for oil-soluble sunscreen intermediate derivatization via acylation or alkylation modification. In pharmaceutical domain, it is adopted as scaffold precursor for local anesthetic and anti-inflammatory candidate synthesis based on benzocaine pharmacophore skeleton. Besides industrial synthesis, high-purity grade is used as lab reference standard for HPLC method development of amino benzoate derivative detection, widely supplied for custom synthesis labs, cosmetic raw material factories and fine chemical R&D institutions around the world.
Low acute oral toxicity data available, irritative to skin and mucous membrane. Direct skin contact will induce erythema and pruritus; flush contaminated skin with large amount of running clean water over 15 minutes once exposure happens. Liquid splashing into eyes causes sharp pain and conjunctival hyperemia; continuously rinse eyes for minimum 15 min and seek medical advice if discomfort remains. Inhalation of mist or volatile vapor irritates nasopharynx and throat leading to cough; all sampling and transferring operations must be finished under well ventilated fume hood with nitrile gloves, splash-proof goggles and organic vapor half-mask. Store separately from foodstuff, strong mineral acids and oxidizing agents; waste liquid and residues shall be disposed in accordance with local hazardous waste control regulations, forbidden arbitrary emission into water and soil environment.
