2,3,4-trifluoroaniline

2,3,4-trifluoroaniline is an organofluorine compound with the molecular formula C6H4F3N and CAS number 3862-73-5. This aromatic amine features three fluorine atoms substituted on positions 2, 3, and 4 of the aniline ring. With a molecular weight of 147.1 g/mol, it belongs to the class of fluorinated aromatic amines used primarily as chemical intermediates in pharmaceutical and agrochemical synthesis.

2,3,4-trifluoroaniline is typically a colorless to pale yellow liquid or crystalline solid at room temperature. The presence of three fluorine atoms significantly influences its physical properties, including increased stability and altered solubility compared to unsubstituted aniline. The compound exhibits moderate volatility and has distinct chemical reactivity due to the electron-withdrawing effects of the fluorine substituents on the aromatic ring.

2,3,4-trifluoroaniline is primarily used as a chemical intermediate in the synthesis of pharmaceuticals, agrochemicals, and specialty chemicals. Its unique substitution pattern makes it valuable for producing fluorinated compounds with specific biological activities. The compound serves as a building block in medicinal chemistry for developing drugs and in agricultural chemistry for creating pesticides and herbicides where fluorine incorporation enhances efficacy and metabolic stability.

2,3,4-trifluoroaniline requires careful handling due to its classification as Acute Tox. 4, Skin Irrit. 2, and Eye Dam. 1. Essential personal protective equipment includes chemical-resistant gloves, safety goggles or face shield, and appropriate respiratory protection. Work should be conducted in well-ventilated areas or under fume hoods. Avoid skin and eye contact, and prevent inhalation of vapors. Emergency eyewash stations and safety showers should be readily accessible.

2,3,4-trifluoroaniline should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. The storage area must be designed to contain spills and prevent environmental release due to its Aquatic Chronic 2 classification. Keep away from incompatible materials such as strong oxidizing agents and acids. Ensure proper labeling with GHS pictograms and maintain appropriate inventory records.

Immediate action is required for any contact with 2,3,4-trifluoroaniline due to its corrosive and toxic properties. For eye contact, flush immediately with copious amounts of water for at least 15 minutes and seek medical attention. For skin contact, remove contaminated clothing and wash thoroughly with soap and water. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention.

2,3,4-trifluoroaniline disposal must comply with local and international hazardous waste regulations due to its toxic and environmentally hazardous properties. The compound cannot be disposed of in regular waste streams and requires treatment by licensed hazardous waste disposal facilities. Incineration at appropriate temperatures or chemical neutralization may be suitable methods. Always consult with waste management professionals and follow applicable environmental regulations including REACH requirements.

2,3,4-trifluoroaniline is classified as ADR Class 9 (Miscellaneous Dangerous Substances), Packing Group III for transportation. This classification requires appropriate packaging, labeling, and documentation according to international dangerous goods regulations. Vehicles must carry proper placards and emergency response information. Drivers require ADR training certification, and shipments must include proper shipping names, UN numbers, and hazard labels. Professional logistics providers experienced with chemical transport should be utilized.

2,3,4-trifluoroaniline is subject to comprehensive chemical regulations including REACH registration requirements in Europe and CLP classification obligations. While not currently listed as an SVHC, its toxic properties require compliance with occupational health and safety regulations, environmental protection laws, and proper chemical inventory reporting. Industrial users must maintain safety data sheets, conduct risk assessments, and implement appropriate control measures according to regulatory requirements.
