Trifluoroacetic acid Trifluoroacetic acid Trifluoroacetic acid (TFA) is an organofluorine compound with the chemical formula CFCOH. It is a structural analogue of acetic acid with all three of the acetyl group’s hydrogen atoms replaced by fluorine atoms and is a colorless liquid with a vinegar like odor. TFA is a stronger acid than acetic acid, having an acid ionisation constant that is approximately 34,000 times higher, as the highly electronegative fluorine atoms and consequent electron-withdrawing nature of the trifluoromethyl group weakens the oxygen-hydrogen bond (allowing for greater acidity) and stabilises the anionic conjugate base. TFA is widely used in organic chemistry for
Trichloroisocyanuric acid It is widely used in civil sanitation for pools and spas, preventing and curing diseases in animal husbandry and fisheries, fruit and vegetable preservation, wastewater treatment, as an algicide for recycled water in industry and air conditioning, in anti shrink treatment for woolens, for treating seeds and in organic chemical synthesis. Trichloroisocyanuric acid as used in swimming pools is easier to handle than chlorine gas. It dissolves slowly in water, but as it reacts, cyanuric acid concentration in the pool will build-up. Trichloroisocyanuric acid Trichloroisocyanuric acid is an organic compound with the formula (CClNO). It is used as an industrial
