4-methylaniline;sulfuric acid

4-methylaniline;sulfuric acid is the sulfate salt of 4-methylaniline (p-toluidine), with CAS number 540-25-0 and molecular formula C7H11NO4S. This aromatic amine compound has a molecular weight of 205.23 g/mol and is classified as a carcinogenic substance (Category 2) under CLP regulation. It presents significant health hazards including acute toxicity and potential cancer risks, requiring careful handling in industrial applications.

4-methylaniline;sulfuric acid is a solid crystalline compound at room temperature, typically appearing as white to off-white crystals. As a sulfate salt of an aromatic amine, it exhibits good water solubility due to its ionic nature. The compound has a molecular weight of 205.23 g/mol and contains both aromatic and ionic functional groups, making it stable under normal conditions but requiring protection from light and moisture.

4-methylaniline;sulfuric acid is primarily used as an intermediate in the synthesis of dyes, pigments, and pharmaceutical compounds. It serves as a precursor in the production of various aromatic compounds and can be employed in analytical chemistry applications. Due to its carcinogenic classification, its use is restricted to professional industrial settings with appropriate safety measures and is not intended for consumer applications.

4-methylaniline;sulfuric acid requires strict safety protocols due to its carcinogenic and toxic properties. Personal protective equipment must include nitrile gloves, safety goggles, and respiratory protection when handling. Work should be conducted in well-ventilated areas or under fume hoods. Avoid skin contact, inhalation, and ingestion. Emergency eyewash stations and safety showers should be readily accessible during handling operations.

4-methylaniline;sulfuric acid should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight. Storage areas must be secured and accessible only to trained personnel due to its carcinogenic classification. Keep away from incompatible materials such as strong oxidizers and bases. Containers should be properly labeled with hazard warnings and stored in secondary containment systems.

In case of skin contact with 4-methylaniline;sulfuric acid, immediately remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush with clean water for 15 minutes and seek immediate medical attention. If inhaled, move to fresh air and seek medical care. For ingestion, do not induce vomiting and obtain immediate medical assistance.

4-methylaniline;sulfuric acid must be disposed of as hazardous chemical waste through licensed waste management companies. Due to its carcinogenic classification and aquatic toxicity, it cannot be discharged into sewers or the environment. Containers should be properly labeled and segregated according to local and European waste regulations. Disposal must comply with REACH and national hazardous waste legislation requirements.

4-methylaniline;sulfuric acid is classified under ADR Class 6.1 (Toxic substances), Packing Group II, indicating moderate toxicity requiring special transport precautions. Packages must bear appropriate hazard labels including GHS08, GHS06, and GHS09 pictograms with 'Danger' signal word. Transportation requires proper documentation, approved packaging, and compliance with dangerous goods regulations for road, rail, and maritime transport within Europe.

4-methylaniline;sulfuric acid is subject to comprehensive European chemical regulations including REACH registration requirements and CLP classification as Carcinogenic Category 2. While not currently listed as an SVHC substance, its carcinogenic properties may require authorization for certain uses. Users must comply with occupational exposure limits, worker protection measures, and environmental discharge restrictions under various EU directives and national legislation.

4-methylaniline;sulfuric acid can be purchased through OYSI, a European distributor specializing in technical chemicals for industrial applications. As a restricted carcinogenic substance, purchase is limited to qualified industrial users with appropriate handling capabilities and safety infrastructure. Buyers must demonstrate legitimate industrial use and comply with regulatory requirements for procurement, handling, and use of carcinogenic substances.
