Naphthalen-2-amine

Naphthalen-2-amine is an aromatic amine compound with the molecular formula C10H9N and CAS number 91-59-8. It consists of a naphthalene ring system with an amino group attached at the 2-position. This organic chemical has a molecular weight of 143.18 g/mol and is classified as a Category 1A carcinogen, making it a substance of significant health concern requiring careful handling and strict safety protocols.

Naphthalen-2-amine is a solid crystalline compound at room temperature, typically appearing as white to pale yellow crystals or powder. It has limited water solubility but dissolves readily in organic solvents such as ethanol and acetone. The compound exhibits characteristic aromatic amine properties and may darken upon exposure to light and air due to oxidation processes.

Naphthalen-2-amine is primarily used as an intermediate in the synthesis of dyes, pigments, and other organic compounds. It serves as a building block in the production of azo dyes, antioxidants, and rubber chemicals. Due to its carcinogenic classification, its industrial applications are highly regulated and restricted in many jurisdictions, with strict controls on occupational exposure.

Naphthalen-2-amine requires strict safety protocols due to its carcinogenic properties. Essential protective equipment includes impervious gloves, protective clothing, and respiratory protection to prevent inhalation. Work should be conducted in well-ventilated areas or under fume extraction systems. Avoid skin contact, inhalation, and ingestion. Regular health monitoring of workers is recommended, and access should be restricted to trained personnel only.

Naphthalen-2-amine should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Storage areas must be secure and accessible only to authorized personnel due to carcinogenic hazards. Keep away from incompatible materials such as strong oxidizing agents. Containers should be properly labeled according to GHS requirements and stored in designated chemical storage facilities.

Immediate action is required for any contact with naphthalen-2-amine. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water. In case of eye contact, flush immediately with plenty of water for at least 15 minutes. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician after any exposure incident.

Naphthalen-2-amine disposal must comply with local and national hazardous waste regulations due to its carcinogenic classification. The substance cannot be disposed of in regular waste streams and requires specialized hazardous waste treatment facilities. Incineration at high temperatures in approved facilities is typically the preferred disposal method. Waste generators must use licensed waste disposal companies and maintain proper documentation for regulatory compliance.

Naphthalen-2-amine is classified under ADR Class 6.1 (toxic substances) Packing Group II, indicating significant transport hazards. Packages must bear appropriate hazard labels including GHS pictograms GHS07, GHS08, and GHS09. Transportation requires proper shipping documentation, trained personnel, and compliance with dangerous goods regulations. Vehicles must carry appropriate emergency equipment and follow designated transport routes where applicable.

Naphthalen-2-amine is subject to extensive regulatory oversight under REACH and CLP regulations in Europe due to its carcinogenic classification. While not currently listed as an SVHC, it faces strict occupational exposure limits and may be subject to authorization requirements. Many countries have implemented workplace restrictions and banned its use in consumer products. Manufacturers and users must comply with comprehensive safety data sheet requirements and exposure assessment obligations.

Naphthalen-2-amine is available through specialized chemical distributors in Europe, including OYSI, which supplies technical-grade chemicals to industrial customers. Due to its hazardous classification, procurement requires proper documentation, safety qualifications, and compliance with regulatory requirements. Buyers must demonstrate legitimate industrial use and appropriate handling capabilities.
