1-nitro-4-phenylbenzene

1-nitro-4-phenylbenzene is an aromatic nitro compound with the molecular formula C12H9NO2 and CAS number 92-93-3. This chemical consists of a biphenyl structure with a nitro group (-NO2) attached to one of the benzene rings. With a molecular weight of 199.2 g/mol, it belongs to the class of nitroaromatic compounds and is classified as a Category 1B carcinogen under GHS classification.

1-nitro-4-phenylbenzene is typically a crystalline solid at room temperature with a characteristic aromatic odor. As an aromatic nitro compound, it exhibits limited water solubility but dissolves well in organic solvents such as alcohols, ethers, and aromatic hydrocarbons. The compound's biphenyl structure contributes to its stability and relatively high melting point, making it suitable for various industrial applications requiring thermal stability.

1-nitro-4-phenylbenzene serves primarily as an intermediate in organic synthesis and pharmaceutical manufacturing. It is commonly used in the production of dyes, pigments, and other aromatic compounds through reduction or substitution reactions. The compound also finds applications in research laboratories for synthetic chemistry studies and as a precursor for the manufacture of specialized chemicals in the fine chemical industry.

1-nitro-4-phenylbenzene requires strict safety measures due to its carcinogenic properties (Carc. 1B classification). Essential personal protective equipment includes nitrile gloves, safety goggles, and respiratory protection in well-ventilated areas or fume hoods. Avoid skin contact, inhalation, and ingestion. Work in designated areas with proper containment measures, and ensure all personnel are trained in handling carcinogenic substances according to occupational safety regulations.

1-nitro-4-phenylbenzene should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Keep away from strong reducing agents, alkali metals, and oxidizing substances that could cause dangerous reactions. Storage areas must be secured and restricted to authorized personnel only, with appropriate warning signs indicating the carcinogenic hazard and environmental risks.

1-nitro-4-phenylbenzene exposure requires immediate action due to its carcinogenic nature. For skin contact, immediately remove contaminated clothing and wash thoroughly with soap and water for at least 15 minutes. If inhaled, move to fresh air immediately. For eye contact, flush with clean water for 15 minutes. Seek immediate medical attention in all cases of exposure and inform medical personnel about the carcinogenic classification of the substance.

1-nitro-4-phenylbenzene disposal must comply with hazardous waste regulations due to its carcinogenic classification and environmental impact. The substance cannot be disposed of in regular waste streams and requires treatment by licensed hazardous waste disposal companies. Incineration at high temperatures in specialized facilities is typically required. All disposal activities must be documented and follow local, national, and EU waste management regulations for carcinogenic substances.

1-nitro-4-phenylbenzene is classified under ADR Class 9 (Miscellaneous dangerous substances), Packing Group III for transportation. Proper packaging includes approved containers with appropriate hazard labels and documentation. Transport vehicles must comply with ADR regulations for Class 9 substances, including proper segregation from incompatible materials and emergency response information. Drivers require appropriate training for transporting hazardous materials under ADR regulations.

1-nitro-4-phenylbenzene is subject to extensive regulatory oversight under REACH and CLP regulations due to its carcinogenic classification (Carc. 1B). Users must comply with authorization requirements, exposure controls, and risk management measures. The substance requires safety data sheets, proper labeling with GHS08 and GHS09 pictograms, and adherence to occupational exposure limits. Environmental release monitoring may also be required under certain jurisdictions.
