1-nitronaphthalene

1-nitronaphthalene is an organic chemical compound with the molecular formula C10H7NO2 and CAS number 27254-36-0. It belongs to the class of nitroaromatic compounds, specifically a nitrated derivative of naphthalene where a nitro group (-NO2) is attached to the first carbon position of the naphthalene ring. With a molecular weight of 173.17 g/mol, this compound appears as a yellowish crystalline solid at room temperature and is primarily used as an intermediate in chemical synthesis processes.

1-nitronaphthalene is a yellowish crystalline solid at room temperature with a melting point around 61-63°C and a boiling point of approximately 304°C. It is practically insoluble in water but readily soluble in organic solvents such as ethanol, benzene, and chloroform. The compound has a characteristic aromatic odor and exhibits low volatility at ambient conditions. Its density is approximately 1.33 g/cm³, and it shows good thermal stability under normal storage conditions.

1-nitronaphthalene serves primarily as an important intermediate in organic synthesis and chemical manufacturing. It is commonly used in the production of dyes, pigments, and various aromatic compounds through reduction or substitution reactions. The compound finds applications in pharmaceutical synthesis as a building block for active ingredients and in the manufacture of specialty chemicals. Additionally, it is utilized in research laboratories for organic synthesis studies and as a starting material for the preparation of aminonaphthalene derivatives.

1-nitronaphthalene should be handled with standard laboratory safety precautions including wearing appropriate personal protective equipment such as safety goggles, gloves, and laboratory coats. Work should be conducted in well-ventilated areas or under fume hoods to avoid inhalation of dust or vapors. Avoid direct skin and eye contact, and prevent ingestion. Use appropriate tools for handling the solid material and ensure proper grounding when transferring to prevent static electricity buildup, as it is classified under ADR Class 4.1.

1-nitronaphthalene should be stored in a cool, dry, and well-ventilated area away from heat sources, ignition sources, and direct sunlight. Keep containers tightly sealed and store in original packaging or suitable chemical-resistant containers. As a Class 4.1 substance, it should be separated from strong oxidizing agents, reducing agents, and incompatible materials. Store at temperatures below 25°C and ensure the storage area is equipped with appropriate fire suppression systems and spill containment measures.

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, rinse immediately with plenty of clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air and monitor breathing. If ingested, do not induce vomiting and seek immediate medical attention. In all cases of significant exposure, consult a physician promptly and provide the safety data sheet.

1-nitronaphthalene must be disposed of in accordance with local, national, and international waste regulations as it is considered hazardous waste. The substance should not be discharged into drains, soil, or water bodies. Disposal should be carried out through licensed waste management companies specialized in handling chemical waste. Incineration at high temperatures in approved facilities is typically the preferred disposal method. Always consult local environmental authorities and waste disposal regulations before disposal, and maintain proper documentation of waste disposal activities.

1-nitronaphthalene is classified under ADR Class 4.1 (flammable solids) Packing Group III for transportation purposes. It must be packaged in UN-approved containers and properly labeled with appropriate hazard markings and documentation. Transport vehicles must comply with ADR regulations including proper placarding, emergency equipment, and driver training requirements. The substance requires proper shipping documentation including dangerous goods declarations and emergency response information. Only authorized carriers experienced in handling hazardous materials should transport this substance.

1-nitronaphthalene is subject to various chemical regulations including REACH (Registration, Evaluation, Authorization and restriction of Chemicals) in the European Union, requiring registration for commercial use. It falls under CLP (Classification, Labelling and Packaging) regulations for proper classification and labeling. The substance is not currently listed as a SVHC (Substance of Very High Concern). Transport is regulated under ADR/RID for road and rail transport. Users must comply with occupational safety regulations and environmental protection laws in their respective jurisdictions.
