Naphthalen-1-amine

Naphthalen-1-amine is an aromatic amine compound with the chemical formula C10H9N and CAS number 134-32-7. It consists of a naphthalene ring system with an amino group (-NH2) attached at the 1-position. This organic compound has a molecular weight of 143.18 g/mol and appears as crystalline solid. It is classified as moderately toxic and poses environmental hazards to aquatic life.

Naphthalen-1-amine is a crystalline solid at room temperature with a characteristic aromatic odor. It typically appears as white to pale yellow crystals that may darken upon exposure to light and air. The compound has limited water solubility but dissolves readily in organic solvents such as ethanol, ether, and benzene. It has a melting point around 50°C and exhibits basic properties due to the amino group.

Naphthalen-1-amine is primarily used as an intermediate in the production of dyes, pigments, and pharmaceuticals. It serves as a building block for synthesizing various azo dyes and other colorants used in textile and printing industries. The compound is also utilized in the manufacture of antioxidants, rubber chemicals, and specialty organic compounds. Additionally, it finds applications in research and development for chemical synthesis purposes.

Naphthalen-1-amine requires careful handling due to its Acute Tox. 4 classification. Always wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or under fume hoods to avoid inhalation. Prevent skin and eye contact, and avoid ingestion. Use non-sparking tools and equipment. Wash hands thoroughly after handling and before eating or drinking.

Naphthalen-1-amine should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep away from oxidizing agents, acids, and incompatible materials. Store in original containers with proper labeling and ensure containers are kept upright. Maintain storage temperature below 25°C and protect from moisture. Implement appropriate fire prevention measures in storage areas.

In case of skin contact with naphthalen-1-amine, immediately remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15 minutes and seek medical attention. If inhaled, move to fresh air and seek medical help if symptoms persist. In case of ingestion, do not induce vomiting and seek immediate medical attention.

Naphthalen-1-amine must be disposed of in accordance with local, national, and international environmental regulations. The compound should be treated as hazardous waste due to its toxicity and environmental impact on aquatic systems. Contact licensed waste disposal companies for proper treatment and disposal. Never discharge into sewers, water bodies, or soil. Small quantities may require incineration at authorized facilities under controlled conditions.

Naphthalen-1-amine is classified under ADR Class 6.1 (Toxic substances) Packing Group III for transportation. It requires proper packaging in UN-approved containers with appropriate labeling including GHS07 and GHS09 pictograms and 'Warning' signal word. Transport documents must include the correct shipping name and UN number. Vehicles must comply with ADR requirements for toxic substances, including proper segregation from incompatible materials.

Naphthalen-1-amine is subject to various European regulations including REACH registration requirements and CLP classification as Acute Tox. 4 and Aquatic Chronic 2. It is not currently listed as a Substance of Very High Concern (SVHC). Users must comply with occupational exposure limits, environmental discharge restrictions, and proper risk assessment procedures. Industrial users may need authorization for certain applications depending on tonnage and use patterns.
