1-nitro-4-phenylbenzene

1-nitro-4-phenylbenzene is an organic chemical compound with the molecular formula C12H9NO2 and CAS number 92-93-3. This aromatic nitro compound consists of two benzene rings connected by a single bond, with one ring bearing a nitro group (-NO2). It has a molecular weight of 199.2 g/mol and is classified as a Category 1B carcinogen, making it a substance of significant health concern requiring careful handling in industrial and research applications.

1-nitro-4-phenylbenzene is typically a crystalline solid at room temperature with characteristic aromatic properties. 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 with the electron-withdrawing nitro group influences its chemical reactivity and physical properties, making it stable under normal conditions but reactive under specific chemical environments.

1-nitro-4-phenylbenzene serves primarily as an intermediate in organic synthesis and chemical manufacturing processes. It is commonly used in the production of dyes, pigments, and pharmaceutical intermediates. The compound also finds applications in research laboratories for synthetic organic chemistry reactions, particularly in the preparation of substituted biphenyl derivatives. Due to its carcinogenic classification, its use is restricted to professional and industrial settings with appropriate safety controls.

1-nitro-4-phenylbenzene requires strict safety protocols due to its Category 1B carcinogenic classification. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and respiratory protection when handling powders or in poorly ventilated areas. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Direct skin contact must be avoided at all times, and proper hygiene practices including thorough handwashing after handling are mandatory.

1-nitro-4-phenylbenzene should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Storage areas must be secure and restricted to authorized personnel due to the compound's carcinogenic properties. The chemical should be kept separate from strong oxidizing agents, reducing agents, and incompatible materials. Proper labeling with hazard warnings and safety data sheets must be readily accessible in storage areas.

Immediate action is required for any contact with 1-nitro-4-phenylbenzene due to its carcinogenic nature. For skin contact, remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15-20 minutes while holding eyelids open. If inhaled, move to fresh air immediately. Seek medical attention promptly for any exposure, informing healthcare providers of the substance's carcinogenic classification.

1-nitro-4-phenylbenzene must be disposed of as hazardous waste through licensed waste management companies in accordance with local and national regulations. The compound cannot be disposed of in regular waste streams due to its carcinogenic properties and potential environmental impact. Waste containers should be properly labeled and stored securely until collection. Incineration at high temperatures in specialized facilities is typically the preferred disposal method, following all applicable environmental and safety regulations.

1-nitro-4-phenylbenzene is classified under ADR Class 9 (Miscellaneous Dangerous Substances), Packing Group III for transportation purposes. It must be packaged in approved containers with proper hazard labels and documentation including transport documents and safety data sheets. Vehicles used for transport should be equipped with appropriate emergency equipment and drivers must be trained in hazardous materials handling. All transport must comply with ADR regulations and national dangerous goods transport requirements.

1-nitro-4-phenylbenzene is subject to extensive regulatory oversight under European REACH and CLP regulations due to its Category 1B carcinogenic classification. The compound requires registration for commercial use and is subject to strict occupational exposure limits and workplace safety requirements. Users must implement risk management measures and maintain detailed records of use and exposure. Additional national regulations may apply depending on the country of use, particularly regarding occupational health and environmental protection.

1-nitro-4-phenylbenzene is available through OYSI, a specialized European distributor of technical chemicals with expertise in hazardous materials handling. As a professional chemical supplier, OYSI ensures proper packaging, labeling, and documentation compliance with European regulations including REACH and CLP requirements. Due to the substance's carcinogenic classification, purchases are restricted to qualified professional and industrial users who can demonstrate appropriate safety measures and legitimate use requirements.
