3-aminophenol

3-aminophenol is an organic chemical compound with the molecular formula C6H7NO and a molecular weight of 109.13 g/mol. It belongs to the aminophenol family, featuring both amino (-NH2) and hydroxyl (-OH) functional groups attached to a benzene ring. This aromatic compound with CAS number 591-27-5 appears as crystalline solid and serves as an important intermediate in various chemical syntheses and industrial applications.

3-aminophenol presents as a crystalline solid at room temperature, typically appearing as light brown to gray crystals or powder. It exhibits good solubility in water and polar organic solvents due to its amino and hydroxyl functional groups. The compound has a characteristic phenolic odor and demonstrates amphoteric properties, meaning it can act as both an acid and a base in chemical reactions.

3-aminophenol serves primarily as an intermediate in pharmaceutical synthesis, particularly in the production of analgesics and antipyretics. It is widely used in the manufacture of hair dyes and cosmetic formulations due to its color-forming properties. Additionally, it functions as a building block in organic synthesis for producing various aromatic compounds and serves as a precursor in the synthesis of certain polymers and specialty chemicals.

3-aminophenol requires careful handling due to its Acute Tox. 4 classification. Personal protective equipment including nitrile gloves, safety goggles, and lab coats should be worn during manipulation. Work in well-ventilated areas or under fume hoods to avoid inhalation exposure. Prevent skin and eye contact, and avoid generating dust. Emergency eyewash stations and safety showers should be readily accessible in work areas.

3-aminophenol should be stored in tightly sealed containers in a cool, dry, and well-ventilated area away from direct sunlight and heat sources. Keep containers upright and properly labeled with hazard information. Store separately from strong oxidizing agents and acids to prevent incompatible reactions. Maintain storage temperatures below 25°C and ensure the storage area has appropriate spill containment measures and is accessible only to authorized personnel.

Immediate action is required upon contact with 3-aminophenol. For skin contact, remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If eyes are affected, flush immediately with clean water for 15 minutes while holding eyelids open. In case of inhalation, move the person to fresh air immediately. Seek medical attention promptly for all exposure routes, especially if symptoms develop.

3-aminophenol disposal must comply with local and national hazardous waste regulations due to its toxicity and environmental hazard classification. The substance cannot be disposed of in regular waste streams or sewers. Contact licensed hazardous waste disposal companies for proper collection and treatment. Small laboratory quantities may be collected through institutional hazardous waste programs. Always consult safety data sheets and local authorities for specific disposal requirements.

3-aminophenol is classified as dangerous goods under ADR regulations with Class 6.1 (toxic substances) and Packing Group III. Transportation requires appropriate UN-specification packaging with proper hazard labels and documentation. Vehicles must carry emergency response information and drivers need hazardous materials training certification. Ensure packages are secure, properly labeled, and accompanied by transport documents specifying the toxic nature of the cargo.

3-aminophenol is subject to various European regulations including REACH registration requirements and CLP classification standards. It carries GHS07 and GHS09 pictograms with "Warning" signal word due to its acute toxicity and aquatic chronic hazards. While not listed as a SVHC (Substance of Very High Concern), it requires proper hazard communication and safety measures in workplace settings according to occupational health regulations.
