Description

Benzoyl Chloride, 3-Mercapto- (9Ci) is a specialized organosulfur compound that serves as a versatile building block in advanced organic synthesis. Its unique structure, combining a reactive benzoyl chloride group with a thiol functionality, makes it a critical intermediate for introducing sulfur-containing moieties into target molecules. This compound is essential for research and development chemists and process engineers in the pharmaceutical, agrochemical, and material science industries seeking to create novel compounds with specific properties.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly those containing thioether or disulfide linkages.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and insecticides where the benzoyl and thiol groups contribute to biological activity.
• Polymer Modification: Acts as a functional monomer or cross-linking agent to introduce sulfur-based functional groups into polymer chains, enhancing properties like adhesion or thermal stability.
• Ligand and Catalyst Preparation: Serves as a precursor for synthesizing chelating ligands used in catalysis and metal complexation.
• Fine Chemical Production: Employed in the multistep synthesis of complex dyes, flavors, and fragrances.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new synthetic pathways and creating novel chemical entities.

Quality Control

Our production of Benzoyl Chloride, 3-Mercapto- adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting key parameters such as assay, impurity profile, and physical characteristics are available upon request. We are committed to meeting the exacting standards required for research and industrial synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, oxidizing agents, and alcohols.
