Description

Benzenebutanol, 1-(4-Methylbenzenesulfonate) is a specialized organic intermediate featuring a butanol chain linked to a benzene ring and protected with a tosylate (p-toluenesulfonate) group. This compound matters as a versatile building block in synthetic organic chemistry, where the tosylate group serves as an excellent leaving group for nucleophilic substitution reactions, enabling precise molecular construction. It is primarily needed by research and development laboratories, pharmaceutical manufacturers, and fine chemical producers for the synthesis of more complex molecules, including potential active pharmaceutical ingredients (APIs) and advanced materials.

Application

• Pharmaceutical Intermediate: Key building block in the multi-step synthesis of novel drug candidates and active pharmaceutical ingredients (APIs).
• Organic Synthesis Reagent: Used as a protected alcohol precursor in nucleophilic substitution and coupling reactions to introduce the phenethyl alcohol moiety.
• Liquid Crystal & Advanced Material Research: Serves as a starting material in the development of organic semiconductors and liquid crystal compounds.
• Agrochemical Synthesis: Intermediate in the production of specialized pesticides and herbicides requiring specific aromatic alcohol derivatives.
• Academic & Industrial R&D: Employed in research laboratories for methodological studies and the development of new synthetic pathways.
• Flavor & Fragrance Chemistry: Potential precursor in the synthesis of aromatic compounds used in fragrance and flavor formulations.
