4-methylaniline;sulfuric acid

4-methylaniline;sulfuric acid is a chemical compound with CAS number 540-25-0 and molecular formula C7H11NO4S. This substance is the sulfate salt form of 4-methylaniline (para-toluidine), created by combining the aromatic amine with sulfuric acid. It has a molecular weight of 205.23 g/mol and is classified as a carcinogenic substance (Category 2) with multiple acute toxicity hazards. The compound presents significant health and environmental risks requiring careful handling procedures.

4-methylaniline;sulfuric acid is a solid compound with molecular formula C7H11NO4S and molecular weight 205.23 g/mol. As a sulfate salt of an aromatic amine, it typically appears as crystalline solid that is water-soluble due to the sulfuric acid component. The compound's properties are influenced by both the organic amine portion and the inorganic acid, making it more stable and less volatile than the free base form while maintaining the chemical reactivity of the aromatic amine group.

4-methylaniline;sulfuric acid is primarily used as an intermediate in the production of dyes, pigments, and other organic compounds. The sulfate form provides better stability and handling characteristics compared to the free amine. It serves as a precursor for manufacturing various azo dyes, pharmaceuticals, and specialty chemicals. Due to its carcinogenic classification, its use is strictly regulated and limited to industrial applications with appropriate safety controls and professional handling requirements.

4-methylaniline;sulfuric acid requires strict safety protocols due to its Carc. 2 and Acute Tox. 3 classifications. Personnel must wear appropriate PPE including chemical-resistant gloves, safety goggles, and respiratory protection. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Skin contact must be avoided as the substance is a skin sensitizer. All handling procedures should follow occupational exposure limits and proper training is essential for workers dealing with this hazardous material.

4-methylaniline;sulfuric acid must be stored in a cool, dry, well-ventilated area away from incompatible materials. Containers should be tightly sealed and properly labeled with hazard information. Storage areas should be equipped with appropriate containment systems and restricted access due to the carcinogenic nature of the compound. The substance should be kept away from oxidizing agents, strong bases, and heat sources. Regular inspection of storage containers and implementation of inventory control measures are essential for safe storage.

Immediate action is required for any contact with 4-methylaniline;sulfuric acid. For skin contact, remove contaminated clothing and flush the affected area with plenty of water for at least 15 minutes. In case of eye contact, rinse immediately with water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air and provide oxygen if breathing is difficult. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician after any exposure incident.

4-methylaniline;sulfuric acid disposal must comply with local, national, and EU waste regulations as hazardous chemical waste. The substance cannot be disposed of in regular waste streams due to its carcinogenic and toxic properties. It requires treatment at authorized hazardous waste facilities with appropriate destruction methods such as high-temperature incineration. Waste containers must be properly labeled and documented. Generators must use licensed waste disposal companies and maintain disposal records as required by environmental regulations.

4-methylaniline;sulfuric acid is classified under ADR as Class 6.1 (toxic substances), Packing Group II. Transportation requires appropriate UN-certified packaging and hazard labeling including toxic substance markings. Vehicles must carry proper documentation including transport documents and emergency response information. Drivers need ADR training certification for dangerous goods transport. The substance must be segregated from incompatible materials during transport and emergency equipment must be available according to ADR regulations.

4-methylaniline;sulfuric acid is subject to extensive EU regulations including REACH registration requirements and CLP classification as Carc. 2. The substance falls under occupational exposure limits and requires risk assessments under workplace safety directives. As a carcinogenic substance, it may be subject to authorization procedures and use restrictions. Companies must maintain safety data sheets, implement exposure control measures, and comply with notification requirements. Additional national regulations may apply depending on the specific use and quantities handled.

4-methylaniline;sulfuric acid is available through OYSI, a specialized European distributor of technical chemicals. As a regulated carcinogenic substance, purchases are restricted to qualified industrial users with appropriate safety infrastructure and regulatory compliance. OYSI provides comprehensive documentation including safety data sheets, certificates of analysis, and regulatory support. Due to the hazardous nature of this compound, procurement requires verification of end-use applications and compliance with REACH and other applicable European chemical regulations.
