Aniline;hydrochloride

Aniline hydrochloride is the hydrochloride salt of aniline, a primary aromatic amine derivative. With the molecular formula C6H8ClN and CAS number 142-04-1, this compound has a molecular weight of 129.59 g/mol. It is classified as a hazardous substance with multiple danger classifications including carcinogenicity (Category 2), mutagenicity (Category 2), and acute toxicity (Category 3). The substance requires careful handling due to its significant health hazards.

Aniline hydrochloride is typically a white to off-white crystalline solid at room temperature. As a hydrochloride salt, it exhibits good water solubility compared to its free base form (aniline). The compound is hygroscopic and may absorb moisture from air. It has a characteristic amine-like odor and is stable under normal storage conditions. The salt form provides better handling characteristics and stability compared to pure aniline, making it more suitable for industrial applications.

Aniline hydrochloride is primarily used as an intermediate in the pharmaceutical and chemical industries. It serves as a precursor for the synthesis of various drugs, dyes, and pigments. The compound is utilized in the production of antioxidants, rubber chemicals, and photographic chemicals. In research laboratories, it functions as a reagent for organic synthesis reactions. Its stable salt form makes it preferable to free aniline for many industrial processes requiring precise dosing and handling.

Aniline hydrochloride requires strict safety measures due to its carcinogenic and mutagenic properties. Always wear appropriate PPE including nitrile gloves, safety goggles, and respiratory protection when handling. Work in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid skin contact and ingestion completely. Use non-sparking tools and ensure proper grounding to prevent static discharge. Regular health monitoring is recommended for workers with potential exposure to this substance.

Aniline hydrochloride should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers away from incompatible materials such as strong oxidizing agents, strong bases, and reactive metals. Store in secondary containment to prevent environmental contamination. Maintain storage temperature below 25°C and protect from moisture due to its hygroscopic nature. Access should be restricted to authorized personnel only due to its hazardous classification.

Aniline hydrochloride exposure requires immediate action due to its toxic nature. For skin contact, immediately remove contaminated clothing and flush affected area with plenty of water for at least 15 minutes. In case of eye contact, rinse immediately with clean water for 15-20 minutes and seek medical attention. If inhaled, move person to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician after any exposure incident.

Aniline hydrochloride disposal must comply with local environmental regulations due to its hazardous classification. The substance cannot be disposed of as regular waste and requires treatment by licensed hazardous waste disposal companies. Small laboratory quantities may be neutralized and treated according to institutional waste management protocols. Never discharge into sewers, waterways, or soil. All contaminated materials including packaging must be handled as hazardous waste. Consult local authorities for specific disposal requirements in your region.

Aniline hydrochloride is classified under ADR Class 6.1 (Toxic substances), Packing Group III for transportation purposes. It must be packaged in UN-approved containers with appropriate hazard labels including GHS pictograms GHS08, GHS06, GHS05, and GHS09. Transport documents must include proper shipping names, UN numbers, and hazard classifications. Drivers require ADR certification for toxic substances. Vehicles must carry appropriate emergency equipment and placards. Segregation requirements must be followed to prevent incompatible cargo mixing.

Aniline hydrochloride is subject to comprehensive chemical regulations including REACH registration requirements in Europe and CLP classification obligations. The substance carries multiple hazard classifications including carcinogenicity and mutagenicity, requiring special handling protocols. Workplace exposure limits apply, and employers must implement appropriate risk management measures. Import/export may require permits or notifications depending on jurisdiction. Users must maintain safety data sheets and provide appropriate worker training. Regular regulatory updates should be monitored for compliance.

Aniline hydrochloride is available through specialized chemical distributors across Europe, including OYSI, which supplies high-quality chemical products to industrial customers throughout the European market. Due to its hazardous classification, purchase typically requires proper business licensing and demonstrated legitimate use. Buyers must ensure compliance with local regulations and implement appropriate safety measures. OYSI provides technical support and regulatory guidance to help customers handle this substance safely and in compliance with applicable European chemical regulations.
