Naphtho[1,2-b]phenanthrene

Naphtho[1,2-b]phenanthrene is a polycyclic aromatic hydrocarbon (PAH) with the molecular formula C22H14 and CAS number 53-70-3. This organic compound has a molecular weight of 278.3 g/mol and consists of fused benzene rings forming a complex aromatic structure. It is classified as a Category 1B carcinogen and poses significant environmental hazards to aquatic life, requiring careful handling and specialized safety measures in industrial applications.

Naphtho[1,2-b]phenanthrene is typically a solid crystalline compound at room temperature with a characteristic aromatic structure. As a polycyclic aromatic hydrocarbon, it exhibits low water solubility but dissolves readily in organic solvents. The compound has a molecular weight of 278.3 g/mol and demonstrates stability under normal conditions. Its aromatic nature contributes to its persistence in the environment and potential bioaccumulation properties.

Naphtho[1,2-b]phenanthrene is primarily used in research applications and as an intermediate in organic synthesis. It serves as a building block for manufacturing specialized chemicals, dyes, and pharmaceuticals. Due to its carcinogenic properties and environmental hazards, its industrial applications are limited and strictly regulated. The compound is mainly utilized in laboratory settings for analytical purposes and scientific research into polycyclic aromatic hydrocarbons.

Naphtho[1,2-b]phenanthrene requires strict safety protocols due to its carcinogenic nature (Category 1B). Personnel must wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection. Work should be conducted in well-ventilated areas or fume hoods to prevent inhalation. Skin and eye contact must be avoided completely. All handling procedures should follow established occupational safety guidelines for carcinogenic substances and environmental protection measures.

Naphtho[1,2-b]phenanthrene must be stored in tightly sealed containers in a cool, dry, and well-ventilated area away from heat sources and incompatible materials. Storage areas should be secured and accessible only to trained personnel due to its carcinogenic classification. The compound should be kept away from oxidizing agents and sources of ignition. Proper labeling with GHS08 and GHS09 pictograms is mandatory, and storage facilities must comply with local regulations for hazardous substances.

Immediate action is critical following contact with naphtho[1,2-b]phenanthrene due to its carcinogenic properties. For skin contact, remove contaminated clothing and wash affected areas thoroughly with soap and water for at least 15 minutes. In case of eye contact, rinse immediately with clean water for 15 minutes and remove contact lenses if present. If inhaled, move to fresh air immediately. Seek medical attention promptly in all cases and inform healthcare providers about the carcinogenic nature of the substance.

Naphtho[1,2-b]phenanthrene disposal requires specialized hazardous waste management due to its carcinogenic and aquatic toxicity properties. The compound cannot be disposed of through regular waste streams and must be handled by licensed hazardous waste contractors. Incineration at high temperatures in approved facilities is typically the preferred disposal method. All disposal activities must comply with local environmental regulations, and waste manifests must properly identify the carcinogenic and environmentally hazardous nature of the material.

Naphtho[1,2-b]phenanthrene is classified as ADR Class 9 (Miscellaneous Dangerous Substances), Packing Group III for transportation purposes. Packages must be properly labeled with appropriate hazard markings and GHS pictograms (GHS08, GHS09). Transport vehicles must carry proper documentation including safety data sheets and emergency response information. Drivers must be trained in handling hazardous materials, and transport must comply with ADR regulations for carcinogenic and environmentally hazardous substances.

Naphtho[1,2-b]phenanthrene is subject to extensive regulatory oversight under REACH, CLP, and national chemical safety regulations. Its classification as a Category 1B carcinogen triggers strict workplace safety requirements and potential use restrictions. The compound's environmental hazard classification (Aquatic Acute 1, Aquatic Chronic 1) subjects it to environmental protection measures. Companies must maintain detailed safety data sheets, implement risk management measures, and ensure compliance with occupational exposure limits and environmental discharge restrictions.

Naphtho[1,2-b]phenanthrene is available through OYSI, a specialized European distributor of technical chemicals. As a regulated carcinogenic substance, procurement requires verification of legitimate use, proper licensing, and compliance with safety regulations. OYSI ensures full regulatory compliance, proper packaging, and comprehensive documentation including safety data sheets. Due to the hazardous nature of this compound, purchases are typically limited to qualified research institutions, laboratories, and industrial users with appropriate safety protocols.
