1-nitronaphthalene

1-nitronaphthalene is an organic chemical compound with the molecular formula C10H7NO2 and CAS number 86-57-7. It belongs to the family of nitroaromatic compounds, featuring a naphthalene ring system with a nitro group (-NO2) attached at the first position. With a molecular weight of 173.17 g/mol, this compound is commonly used as an intermediate in chemical synthesis and manufacturing processes.

1-nitronaphthalene is typically a pale yellow to yellow crystalline solid at room temperature with a characteristic aromatic odor. It has limited solubility in water but dissolves readily in organic solvents such as ethanol, benzene, and ether. The compound exhibits typical properties of nitroaromatic compounds, including relatively high melting and boiling points due to intermolecular forces between the aromatic rings and nitro groups.

1-nitronaphthalene is primarily used as an intermediate in the synthesis of dyes, pigments, and pharmaceuticals. It serves as a precursor for manufacturing various aromatic compounds through reduction reactions to form aminonaphthalenes. The compound is also utilized in research applications and as a building block in organic synthesis for producing specialty chemicals and advanced materials in industrial processes.

Safe handling of 1-nitronaphthalene requires appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to avoid inhalation of vapors or dust. Avoid skin and eye contact, and prevent ingestion. Use non-sparking tools and equipment, and ensure proper grounding to prevent static electricity buildup during handling operations.

1-nitronaphthalene should be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Keep containers tightly closed and protect from light and moisture. Store away from incompatible materials such as strong oxidizing agents, reducing agents, and alkalis. Maintain storage temperatures below 25°C and ensure adequate fire prevention measures are in place due to its flammable solid classification.

In case of skin contact with 1-nitronaphthalene, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15-20 minutes and seek medical attention. If inhaled, move the person to fresh air and seek medical advice if respiratory irritation occurs. In case of ingestion, do not induce vomiting and seek immediate medical attention.

1-nitronaphthalene must be disposed of in accordance with local, national, and international waste regulations. The compound should be treated as hazardous chemical waste and handed over to licensed waste disposal companies. Incineration at high temperatures in appropriate facilities is typically the preferred disposal method. Never dispose of this substance in regular waste streams, sewage systems, or the environment. Contact specialized waste management services for proper collection and treatment.

1-nitronaphthalene is classified under ADR as Class 4.1 (Flammable solids), Packing Group III. Transportation requires appropriate packaging according to ADR regulations, including proper labeling and documentation. Packages must be marked with the correct shipping name and UN number. Vehicles transporting this substance must comply with ADR requirements for flammable solids, including appropriate equipment and driver certification for hazardous materials transport.

1-nitronaphthalene is subject to standard chemical regulations including REACH registration requirements in the European Union. The substance is not classified as a Substance of Very High Concern (SVHC) under REACH. However, it must comply with CLP regulation requirements for classification, labeling, and packaging. Users should maintain safety data sheets and follow occupational exposure limits where established by national authorities.
