2-nitronaphthalene

2-nitronaphthalene is an organic chemical compound with the molecular formula C10H7NO2 and CAS number 581-89-5. It belongs to the nitroaromatic family, consisting of a naphthalene ring with a nitro group attached at the 2-position. With a molecular weight of 173.17 g/mol, this compound is classified as a Category 1B carcinogen and poses chronic aquatic toxicity hazards. It requires careful handling due to its serious health and environmental risks.

2-nitronaphthalene is typically a yellowish crystalline solid at room temperature with characteristic aromatic odor. As a nitroaromatic compound, it exhibits limited water solubility but dissolves well in organic solvents such as alcohols, ethers, and aromatic hydrocarbons. The compound has a molecular weight of 173.17 g/mol and contains both electron-withdrawing nitro group and aromatic naphthalene structure, influencing its chemical reactivity and physical behavior.

2-nitronaphthalene serves primarily as an intermediate in organic synthesis and chemical manufacturing processes. It is commonly used in the production of dyes, pigments, and other specialty chemicals. The compound also finds application in pharmaceutical synthesis as a building block for various drug compounds. Additionally, it may be utilized in research and development activities within the chemical industry for developing new materials and chemical processes.

2-nitronaphthalene requires strict safety measures due to its carcinogenic properties (Carc. 1B classification). Always wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection. Work in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid skin contact and ingestion completely. Use proper engineering controls, maintain good hygiene practices, and ensure all personnel are trained on the specific hazards associated with this dangerous substance.

2-nitronaphthalene should be stored in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers tightly closed and properly labeled with hazard information. Store separately from incompatible materials such as strong oxidizers, reducing agents, and bases. Ensure storage areas have appropriate fire safety measures since the compound is classified under ADR Class 4.1 (flammable solids). Regular inspection of storage conditions and container integrity is essential for safe storage.

In case of skin contact with 2-nitronaphthalene, immediately remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. If inhaled, move the person to fresh air immediately and seek medical attention. For eye contact, flush eyes with clean water for at least 15 minutes. If ingested, do not induce vomiting and seek immediate medical help. Always consult a physician and provide the safety data sheet information.

2-nitronaphthalene disposal must comply with local, national, and international hazardous waste regulations due to its carcinogenic and environmentally hazardous properties. The compound cannot be disposed of in regular waste streams and requires specialized hazardous waste treatment. Contact licensed hazardous waste disposal companies for proper collection and treatment. Incineration at appropriate temperatures in authorized facilities is typically the preferred disposal method. Always maintain proper documentation for waste tracking purposes.

2-nitronaphthalene is classified under ADR Class 4.1 (flammable solids) Packing Group III for transportation purposes. It must be packaged according to specific ADR packaging instructions and properly labeled with appropriate hazard labels and UN identification numbers. Transportation should only be carried out by qualified personnel familiar with dangerous goods regulations. Vehicles must be equipped with appropriate safety equipment, and transport documents must accompany the shipment at all times.

2-nitronaphthalene is subject to comprehensive chemical safety regulations including REACH registration requirements in Europe and CLP classification as Carc. 1B and Aquatic Chronic 2. The compound requires safety data sheets, proper labeling with GHS08 and GHS09 pictograms, and "Danger" signal word. Users must implement risk management measures and comply with occupational exposure limits. Additional restrictions may apply for specific uses, and the substance requires careful monitoring throughout the supply chain.
