Trifluoroacetic Acid CAS 76-05-1

1. Trifluoroacetic acid is widely used as a volatile ion-pairing agent in reversed-phase liquid chromatography (RPLC) for peptide and protein analysis, enhancing separation efficiency and detection sensitivity .
2. Trifluoroacetic acid CAS 76-05-1 serves as a strong organic acid and versatile solvent in organic synthesis, particularly for deprotection reactions in peptide chemistry and as a catalyst in various transformations .
3. Trifluoroacetic acid is employed in the synthesis of pharmaceuticals and agrochemicals, including as a source of the trifluoromethyl group in drug development, and in surface modification of polymers and fibers .

1. Store Trifluoroacetic acid in a tightly sealed corrosion-resistant container (glass or PTFE) in a cool, dry, well-ventilated area, away from heat, sparks, and incompatible materials .
2. Keep Trifluoroacetic acid CAS 76-05-1 strictly away from strong oxidizing agents, strong bases, and metals, as Trifluoroacetic acid is highly corrosive and reacts violently with water, releasing toxic fumes .
3. Handle Trifluoroacetic acid using appropriate personal protective equipment including acid-resistant gloves (butyl rubber), face shield, and in a fume hood, as Trifluoroacetic acid causes severe burns and respiratory damage .

1. Isolate the spill area, wear full protective equipment including self-contained breathing apparatus, and contain liquid Trifluoroacetic acid using dry inert absorbent material like sand, preventing entry into drains or waterways .
2. Neutralize Trifluoroacetic acid CAS 76-05-1 carefully with soda ash or lime, then collect into sealed, labeled corrosion-resistant containers for disposal according to hazardous material regulations .
3. Personnel cleaning Trifluoroacetic acid spills must use non-sparking tools and ensure adequate ventilation, as vapors may form explosive concentrations and Trifluoroacetic acid is classified for transport (UN 2699, Hazard Class 8, Packing Group I) .

1. Trifluoroacetic acid is a corrosive substance (GHS05, Danger) causing severe skin burns, serious eye damage (H314, H318), and is harmful if swallowed (H302) or inhaled (H332) .
2. Trifluoroacetic acid CAS 76-05-1 has an NFPA health rating of 4 (severe hazard), flash point not applicable (non-flammable), but thermal decomposition produces toxic fumes including carbon oxides and hydrogen fluoride .
3. Trifluoroacetic acid is very toxic to aquatic life with long-lasting effects (H400, H412), has a boiling point of 72°C, density of 1.535 g/mL, and is miscible with water .
