4-methylbenzenesulfonohydrazide

4-methylbenzenesulfonohydrazide is an organic chemical compound with the molecular formula C7H10N2O2S and a molecular weight of 186.23 g/mol. This substance belongs to the sulfonohydrazide family and is characterized by a benzene ring substituted with a methyl group and a sulfonohydrazide functional group. It is classified as a self-reactive substance of type D, indicating its potential for exothermic decomposition under certain conditions.

4-methylbenzenesulfonohydrazide is typically a solid crystalline compound at room temperature. The substance contains both hydrophilic (sulfonohydrazide) and lipophilic (methylbenzene) moieties, affecting its solubility characteristics. As a sulfonohydrazide derivative, it may exhibit moderate solubility in polar solvents. The compound's self-reactive nature indicates thermal instability, requiring careful temperature control during handling and storage to prevent decomposition reactions.

4-methylbenzenesulfonohydrazide is primarily used as a chemical intermediate in organic synthesis and pharmaceutical manufacturing. It serves as a building block for the production of more complex molecules, particularly in the development of active pharmaceutical ingredients. The compound may also find applications in specialty chemical manufacturing, research and development activities, and as a reagent in analytical chemistry procedures requiring sulfonohydrazide functionality.

4-methylbenzenesulfonohydrazide requires careful handling due to its self-reactive nature and 'Danger' signal word classification. Operators must wear appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods. Avoid exposure to heat sources, friction, and shock. Ground all equipment to prevent static electricity buildup, and ensure fire extinguishing equipment is readily available.

4-methylbenzenesulfonohydrazide must be stored in cool, dry conditions away from heat sources, direct sunlight, and incompatible materials. As a self-reactive substance, it requires temperature control to prevent decomposition. Store in original, tightly sealed containers in a well-ventilated area. Keep away from oxidizing agents, acids, and bases. Storage areas should be equipped with appropriate fire suppression systems and emergency response equipment.

4-methylbenzenesulfonohydrazide exposure requires immediate action depending on the route of contact. For skin contact, remove contaminated clothing and rinse affected areas with plenty of water for at least 15 minutes. In case of eye contact, flush immediately with water and seek medical attention. If inhaled, move the person to fresh air and monitor breathing. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult the safety data sheet for specific emergency procedures.

4-methylbenzenesulfonohydrazide disposal must comply with local, national, and European waste regulations due to its self-reactive classification. The substance cannot be disposed of with regular waste and requires specialized hazardous waste treatment. Contact licensed waste disposal companies experienced with self-reactive materials. Ensure proper documentation and tracking throughout the disposal process. Small quantities may require neutralization or stabilization before disposal, following regulatory guidelines.

4-methylbenzenesulfonohydrazide is classified under ADR Class 4.1 as a flammable solid with self-reactive properties. Transportation requires compliance with dangerous goods regulations, including proper packaging, labeling, and documentation. Packages must display appropriate hazard labels and UN identification numbers. Drivers need ADR certification, and vehicles must carry emergency equipment. Temperature control during transport may be necessary to prevent decomposition. Consult current ADR regulations for specific packaging and transport requirements.

4-methylbenzenesulfonohydrazide is subject to European REACH regulation requiring registration for manufacture or import above one tonne annually. The substance falls under CLP regulation for classification and labeling as a self-reactive material. It is not currently listed as an SVHC (Substance of Very High Concern). Industrial users must comply with occupational health and safety regulations, proper risk assessment, and worker protection measures. Transport regulations under ADR also apply for shipment.

4-methylbenzenesulfonohydrazide is available through OYSI, a specialized European distributor of technical chemicals. OYSI provides reliable supply of this self-reactive compound with proper safety documentation and regulatory compliance support. As a technical chemical requiring specialized handling, it's essential to source from experienced distributors who understand the safety requirements and can provide appropriate packaging, documentation, and technical support for safe handling and use.
