Trifluoroacetic Anhydride (TFAA), with the CAS number 407-25-0, is a potent and highly reactive chemical intermediate widely used in organic synthesis. As a clear, colorless liquid with a characteristic odor, it is indispensable for many complex chemical transformations. NINGBO INNO PHARMCHEM CO.,LTD., a dedicated manufacturer and supplier, provides this vital reagent and emphasizes the importance of understanding its properties and safe handling procedures.

Key Properties of Trifluoroacetic Anhydride:

• Chemical Formula: C4F6O3
• Molar Mass: 210.03 g/mol
• Appearance: Clear, colorless liquid
• Melting Point: Approximately -63.5 °C
• Boiling Point: Approximately 39.5-40 °C
• Density: ~1.511 g/mL at 20 °C
• Solubility: Miscible with various organic solvents like benzene, dichloromethane, and ether.
• Reactivity: Highly reactive, particularly with nucleophiles.
• Moisture Sensitivity: Reacts readily with water, hydrolyzing to trifluoroacetic acid and releasing heat. This reaction can also liberate flammable hydrogen gas under certain conditions, making it crucial to handle in dry environments.
• Corrosivity: TFAA is corrosive and can cause severe skin and eye irritation or burns.

Safe Handling and Storage:

Due to its hazardous nature, strict safety protocols must be followed when working with Trifluoroacetic Anhydride:

• Personal Protective Equipment (PPE): Always wear appropriate PPE, including chemical-resistant gloves (e.g., nitrile, neoprene), safety goggles or a face shield, and protective clothing.
• Ventilation: Work in a well-ventilated area or, preferably, under a chemical fume hood to avoid inhalation of vapors.
• Incompatibilities: TFAA is incompatible with strong oxidizing agents, water, and certain other reactive compounds. Always consult the Safety Data Sheet (SDS) for a comprehensive list.
• Storage: Store TFAA in a tightly sealed container in a cool, dry, and well-ventilated area, away from incompatible materials and moisture. Refrigeration (2-8°C) is often recommended for long-term storage to maintain purity.
• Spill Management: In case of a spill, evacuate the area and use appropriate absorbent materials and neutralization agents as per the SDS guidelines. Ensure proper disposal of contaminated materials.
