Description

Benzoyl Chloride, 2-[(1-Methylethyl)Thio]- (9Ci) is a specialized organosulfur derivative of benzoyl chloride, characterized by the presence of an isopropylthio substituent at the ortho position. This structural feature makes it a valuable high-purity synthetic intermediate for constructing complex molecules in advanced chemical synthesis. It is primarily sought by R&D and production teams in the pharmaceutical and agrochemical industries for developing novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of proprietary drug candidates, particularly those requiring a thioether-linked aromatic moiety.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides, where the isopropylthio group can influence biological activity.
• Ligand and Catalyst Development: Serves as a precursor for creating specialized ligands used in transition metal catalysis and organometallic chemistry.
• Material Science Research: Employed in the development of novel polymers or functional materials with specific sulfur-containing aromatic units.
• Custom Synthesis and Contract Manufacturing: A critical reagent for fine chemical manufacturers offering bespoke synthesis services to the life sciences sector.

Quality Control

Every batch of our Benzoyl Chloride, 2-[(1-Methylethyl)Thio]- (9Ci) is produced under strict quality management protocols. We provide comprehensive Certificates of Analysis (COA) that detail purity, identity, and impurity profiles, ensuring traceability and compliance with your project specifications. Our quality systems are designed to support cGMP and ISO standards for advanced chemical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic and strong acid/organic solvent nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Recommended storage temperature is 2-8°C for long-term stability.
