Description

1H-Benzimidazole-1-Sulfinylchloride(9Ci) is a specialized sulfinyl chloride derivative of benzimidazole, serving as a key reactive intermediate in advanced organic synthesis. Its primary value lies in its ability to act as a versatile electrophilic sulfinylating or sulfonamide-forming agent, enabling the construction of complex heterocyclic and pharmaceutical scaffolds. This high-purity building block is essential for research and development chemists in the pharmaceutical, agrochemical, and material science industries who require precise and reliable synthetic tools.

Application

• Pharmaceutical Intermediate: Critical for the synthesis of novel benzimidazole-based drug candidates, including potential antivirals, antifungals, and kinase inhibitors.
• Agrochemical Synthesis: Used in the development of new generation fungicides and herbicides that leverage the benzimidazole pharmacophore.
• Chemical Research & Development: Employed as a specialized reagent for introducing the sulfinyl or sulfonamide moiety into complex molecules in academic and industrial R&D settings.
• Material Science Precursor: Acts as a monomer or functionalization agent in the creation of advanced polymers and functional materials with specific electronic or surface properties.
• Custom Synthesis & Contract Manufacturing: A vital building block for CDMOs (Contract Development and Manufacturing Organizations) producing bespoke compounds for client projects.

Quality Control

Our 1H-Benzimidazole-1-Sulfinylchloride(9Ci) is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity, typically meeting standards suitable for research and fine chemical synthesis. Each lot is analyzed using advanced techniques including HPLC, NMR, and IR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (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, and open flame.
