For industrial procurement and application, understanding the precise technical specifications of a chemical intermediate is critical for ensuring successful outcomes. NINGBO INNO PHARMCHEM CO.,LTD. provides detailed information on 2-Nitrobenzenesulfonyl Chloride to meet the rigorous demands of industrial users. This includes key quality parameters that guarantee its performance in synthesis and manufacturing processes.

The primary specification for 2-Nitrobenzenesulfonyl Chloride is its purity, typically stated as ≥97% or ≥99% when assessed by methods such as HPLC or titration. This high purity level is essential for achieving efficient reaction yields and minimizing unwanted by-products in sensitive synthesis pathways, particularly in pharmaceutical manufacturing. The physical appearance is also a key identifier: an off-white to yellow to orange crystalline powder is indicative of a product meeting quality standards.

Other important technical details include its molecular formula (C6H4ClNO4S) and molecular weight (221.62 g/mol), which are fundamental for stoichiometric calculations in chemical reactions. The CAS number, 1694-92-4, serves as a unique identifier for the compound. The melting point, consistently reported in the range of 63-67°C, is a critical parameter for verifying the compound's identity and purity.

For industrial applications, understanding the compound's behavior in different environments is also important. Its solubility in various organic solvents like toluene, THF, and dichloromethane, while being insoluble in water, guides its selection for specific reaction media. Furthermore, its moisture-sensitive nature necessitates careful attention to packaging and storage. Typically, it is supplied in moisture-proof containers to preserve its quality during transport and storage.

NINGBO INNO PHARMCHEM CO.,LTD. ensures that each batch of 2-Nitrobenzenesulfonyl Chloride undergoes stringent quality control testing to meet these specifications. Certificates of Analysis (CoA) are available upon request, providing detailed results for purity, melting range, and other critical parameters, ensuring transparency and traceability for our industrial clients. This commitment to quality and documentation is vital for industries that rely on precise chemical inputs for their manufacturing processes.

By providing clear and accurate technical specifications, NINGBO INNO PHARMCHEM CO.,LTD. empowers industries to confidently integrate 2-Nitrobenzenesulfonyl Chloride into their production cycles, whether for pharmaceutical intermediates, dyestuffs, or other complex organic synthesis applications.
