2-phenylsulfanylaniline is an organic chemical compound with the molecular formula C12H11NS and CAS number 1134-94-7. This aromatic amine features a phenyl group connected to an aniline moiety through a sulfur bridge. With a molecular weight of 201.29 g/mol, it belongs to the class of organosulfur compounds and is primarily used as an intermediate in chemical synthesis and pharmaceutical applications.

2-phenylsulfanylaniline is a solid organic compound at room temperature with a molecular weight of 201.29 g/mol. As an aromatic amine containing sulfur, it typically appears as a crystalline powder with characteristic properties of substituted anilines. The compound contains both nitrogen and sulfur heteroatoms, which influence its solubility behavior and chemical reactivity in various solvents and reaction conditions.

2-phenylsulfanylaniline serves primarily as a chemical intermediate in organic synthesis and pharmaceutical manufacturing. Its unique structure, combining aniline and thioether functionalities, makes it valuable for producing specialized compounds in drug development, dye synthesis, and materials science. The compound is particularly useful in research applications where both aromatic amine and sulfur-containing moieties are required for specific chemical transformations.

2-phenylsulfanylaniline must be handled with appropriate personal protective equipment due to its skin sensitization properties (Skin Sens. 1). Wear protective gloves, safety goggles, and suitable clothing to prevent skin contact. Ensure adequate ventilation in the work area and avoid generating dust or aerosols. Handle only in well-ventilated areas or under fume hoods to minimize inhalation risks and prevent skin sensitization reactions.

2-phenylsulfanylaniline should be stored in tightly sealed containers in a cool, dry, and well-ventilated area away from heat sources and incompatible materials. Keep containers properly labeled and protect from moisture and direct sunlight. Store separately from strong oxidizers and acids to prevent unwanted reactions. Maintain storage temperatures according to supplier specifications and ensure proper inventory rotation to maintain product quality.

In case of skin contact with 2-phenylsulfanylaniline, immediately remove contaminated clothing and wash the affected area thoroughly with soap and plenty of water for at least 15 minutes. If eye contact occurs, flush immediately with clean water for 15 minutes while holding eyelids open. Seek medical attention if irritation develops or persists, especially given the compound's skin sensitization potential. Remove to fresh air if inhaled.

2-phenylsulfanylaniline must be disposed of through licensed hazardous waste disposal facilities in accordance with local and European waste regulations. Do not discharge into sewers or waterways due to its aquatic chronic toxicity (Aquatic Chronic 2). Collect waste in appropriate containers, properly label them, and arrange collection through certified waste management companies. Follow all applicable environmental regulations for hazardous chemical waste disposal.

2-phenylsulfanylaniline is classified as ADR Class 9 (Miscellaneous Dangerous Goods), Packing Group III for transportation purposes. It must be packaged in approved containers and properly labeled according to ADR regulations. Transport documentation must include the correct shipping name, UN number, and hazard class. Ensure vehicles are properly placarded and drivers hold appropriate dangerous goods certifications for Class 9 materials.

2-phenylsulfanylaniline is subject to European chemical regulations including REACH and CLP classification requirements. It is classified as Skin Sens. 1 and Aquatic Chronic 2, requiring appropriate labeling with GHS07 and GHS09 pictograms and 'Warning' signal word. The compound is not currently listed as an SVHC (Substance of Very High Concern), but users must comply with standard chemical safety and environmental protection requirements.
