N,N-dimethylsulfamoyl chloride

N,N-dimethylsulfamoyl chloride is a reactive organosulfur compound with the molecular formula C2H6ClNO2S and CAS number 13360-57-1. This chemical intermediate has a molecular weight of 143.59 g/mol and belongs to the sulfamoyl chloride family. It is classified as a highly hazardous substance with carcinogenic properties (Category 1B) and acute toxicity. The compound is primarily used in organic synthesis as a reagent for introducing dimethylsulfamoyl groups into target molecules.

N,N-dimethylsulfamoyl chloride is typically a colorless to pale yellow liquid at room temperature with a pungent, irritating odor. The compound is moisture-sensitive and reacts readily with water, releasing hydrogen chloride gas. It has good solubility in organic solvents such as dichloromethane, chloroform, and acetonitrile, but decomposes in protic solvents. Due to its reactive nature, it should be handled under anhydrous conditions and stored away from moisture and nucleophiles.

N,N-dimethylsulfamoyl chloride is primarily used as a chemical intermediate in pharmaceutical and agrochemical synthesis. It serves as a sulfonylating agent for the preparation of sulfonamide derivatives, which are important scaffolds in drug discovery. The compound is also employed in the synthesis of herbicides, fungicides, and other biologically active compounds. Additionally, it finds applications in academic research laboratories for the development of new synthetic methodologies and the preparation of specialized organic compounds.

N,N-dimethylsulfamoyl chloride requires strict safety measures due to its carcinogenic and corrosive properties. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, face shield, and a lab coat. Work must be conducted in a well-ventilated fume hood to prevent inhalation exposure. Avoid skin and eye contact completely, as the compound causes severe burns. Use appropriate containment measures to prevent spills, and ensure emergency shower and eyewash stations are readily accessible during handling operations.

N,N-dimethylsulfamoyl chloride must be stored in a cool, dry, well-ventilated area away from moisture, heat sources, and incompatible materials. Use tightly sealed, moisture-proof containers made of compatible materials such as glass or PTFE-lined vessels. Store separately from alcohols, amines, water, and other nucleophiles that can cause decomposition. Keep containers upright and properly labeled with hazard information. Storage areas should have appropriate containment systems and be accessible only to trained personnel wearing proper protective equipment.

N,N-dimethylsulfamoyl chloride contact requires immediate emergency response due to its corrosive nature. For skin contact, immediately remove contaminated clothing and flush the affected area with copious amounts of water for at least 15 minutes. In case of eye contact, rinse immediately with water for at least 15 minutes while holding eyelids open. If inhaled, move the person to fresh air immediately. Do not induce vomiting if ingested. Seek immediate medical attention in all cases of exposure and provide safety data sheet information to medical personnel.

N,N-dimethylsulfamoyl chloride disposal must comply with local, national, and international hazardous waste regulations due to its carcinogenic classification. The substance cannot be disposed of through regular waste streams and requires specialized hazardous waste treatment. Contact licensed hazardous waste disposal companies for proper collection and treatment. Small quantities may be neutralized carefully under controlled conditions by trained personnel, but this should only be done following established protocols. Always consult with waste management specialists and regulatory authorities before disposal.

N,N-dimethylsulfamoyl chloride is classified under ADR Class 6.1 (Toxic substances), Packing Group II, indicating significant transport hazards. Shipments must comply with dangerous goods regulations including proper packaging in UN-approved containers, appropriate labeling with GHS pictograms (GHS05, GHS06, GHS08), and dangerous goods documentation. Transport vehicles require placarding and drivers must have hazardous materials training. The substance must be segregated from incompatible materials during transport and emergency response information must accompany shipments.

N,N-dimethylsulfamoyl chloride is subject to extensive regulatory oversight due to its carcinogenic properties and high toxicity. Under EU REACH regulation, it requires registration for manufacture or import above tonnage thresholds. The CLP regulation mandates specific hazard classification and labeling requirements. As a Category 1B carcinogen, it may face restrictions on use and requires occupational exposure controls. Users must implement risk management measures and may need authorization for certain applications. Always consult current regulatory databases for the latest restrictions and requirements.
