Applications & Industries

Pharmaceutical Active Ingredient Synthesis

Lifitegrast Manufacturing: Key starting material for dry eye medication (Xiidra®). Reaction with 2-aminoethanol produces tetrahydroisoquinoline intermediates.

Analgesic Drug Production: Critical intermediate for headache medications through reaction with tropine and hydrogen chloride, providing stable pharmaceutical properties.

Manufacturing: Reacts with arylamine compounds at 60°C in DMF to yield dichlorobenzamide derivatives (compounds 4-14) in high yields.

Herbicide & Pesticide Manufacturing

Propyzamide Synthesis: Critical intermediate for propyzamide herbicide production - a selective pre-emergence herbicide used for broadleaf weed control.

Oxaziclomefone Production: Key building block for oxaziclomefone herbicide synthesis.
