CAS 76-05-1: Trifluoroacetic acid
Description:Trifluoroacetic acid (TFA) is a colorless, pungent liquid with the chemical formula C2HF3O2. It is a strong organic acid, characterized by the presence of three fluorine atoms attached to the carbon backbone, which significantly enhances its acidity compared to acetic acid. TFA is highly soluble in water and many organic solvents, making it a versatile reagent in various chemical reactions. Its strong acidity is utilized in organic synthesis, particularly in the preparation of trifluoroacetyl derivatives and as a catalyst in certain reactions. TFA is also known for its ability to stabilize carbanions and is commonly used in peptide synthesis and protein chemistry. However, it is important to handle TFA with care, as it is corrosive and can cause severe burns upon contact with skin. Additionally, TFA is considered environmentally persistent, and its use is regulated in some regions due to potential ecological impacts. Overall, trifluoroacetic acid is a valuable compound in both industrial and laboratory settings, owing to its unique chemical properties.
