Methyl Trifluoroacetate CAS 431-47-0

1. Methyl trifluoroacetate CAS 431-47-0 is a key reagent for the trifluoroacetylation of amines under mild conditions and, in the presence of tetramethylguanidine, for the N-acylation of amino acids .
2. Methyl trifluoroacetate is an important intermediate in the synthesis of fluorinated organic compounds, which are valuable in pharmaceutical and agricultural chemical development .
3. Methyl trifluoroacetate is utilized in polymer chemistry to create fluorinated polymers with enhanced chemical resistance and in analytical chemistry for derivatizing alcohols and amines to improve detection sensitivity .

1. Store Methyl trifluoroacetate CAS 431-47-0 in a tightly sealed container under inert gas in a cool, dry, well-ventilated place, as Methyl trifluoroacetate is moisture sensitive .
2. Keep Methyl trifluoroacetate away from heat, sparks, open flames, and incompatible materials including strong oxidizing agents and strong bases .
3. Handle Methyl trifluoroacetate using appropriate personal protective equipment including butyl-rubber gloves, tightly fitting safety goggles, face shield, and in a fume hood, ensuring containers are grounded to prevent electrostatic discharge .

1. Isolate the spill area, eliminate all ignition sources, and contain liquid Methyl trifluoroacetate CAS 431-47-0 using dry inert absorbent material like sand, preventing entry into drains or waterways .
2. Collect absorbed Methyl trifluoroacetate using an electrically protected vacuum cleaner or by wet-brushing into sealed, labeled containers for disposal according to environmental regulations .
3. Personnel cleaning Methyl trifluoroacetate spills must wear full protective equipment including self-contained breathing apparatus, as Methyl trifluoroacetate is a highly flammable liquid (flash point -20°C) with corrosive properties .

1. Methyl trifluoroacetate CAS 431-47-0 is a highly flammable liquid and vapor (H225) with GHS signal word "Danger", causing severe skin burns and serious eye damage.
2. Methyl trifluoroacetate is harmful if swallowed (H302) and may cause corrosive injuries to the upper respiratory tract and lungs if inhaled; Methyl trifluoroacetate is also a lachrymator (tear gas agent) .
3. Methyl trifluoroacetate has a boiling point of 43°C, density of 1.29 g/mL, is slightly soluble in water (8g/L), and is classified for transport as a flammable liquid; combustion produces toxic fumes including carbon oxides and hydrogen fluoride .
