Description

Benzoyl Chloride, 4-[(1-Methylethyl)Thio]- (9Ci) CAS NO 69708-37-8 is a specialized organosulfur derivative of benzoyl chloride, characterized by the presence of an isopropylthio substituent at the para position. This functionalization makes it a valuable high-purity chemical intermediate for synthesizing more complex molecules in advanced research and industrial applications. It is primarily sought by pharmaceutical, agrochemical, and material science sectors for the development of novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly those requiring sulfur-containing pharmacophores.
• Agrochemical Synthesis: Used in the production of advanced pesticides, herbicides, and fungicides where the isopropylthio group enhances biological activity.
• Liquid Crystal & OLED Material Precursor: Serves as a critical intermediate in the manufacture of specialty chemicals for electronic displays and organic light-emitting diodes.
• Polymer Modification Agent: Employed to introduce specific functional groups into polymer chains, altering physical properties like solubility and thermal stability.
• Organic Synthesis Reagent: A versatile acylating agent in research laboratories for the preparation of esters, amides, and ketones under controlled conditions.
• Dye & Pigment Manufacturing: Used in the synthesis of specialized sulfur-based dyes and high-performance pigments.
