Description

High Performance Liquid Chromatography (HPLC) Method for Analysis of TFA (Trifluoroacetic Acid) , Acetic Acid , Chloroacetic acid , Dichloroacetic acid , Trichloroacetic acid , Difluoroacetic acid .

Acetic Acid is the second simplest carboxylic acid with the chemical formula CH 3 COOH . It is well known for being the active ingredient in vinegar, leading to the belief that it is the earliest mass produced acid, dating back to 3BC. Outside of it’s use in food and household matters, it is also used in production of vinyl acetate and cellulose acetate.

Chloroacetic Acid , also known as monochloroacetic acid (MCA), is a very toxic acid with the chemical formula ClCH 2 CO 2 H . It is most often used in the production of other chemicals such as phenoxy herbicides, carboxymethyl cellulose, and carboxymethyl starch. It is considered extremely hazardous as it can cause burns on skin and eyes as well as be fatal if inhaled or swallowed.

Difluoroacetic Acid (DFA) is a dihalogenocarboxylic acid with the chemical formula CHF 2 COOH . As a solution, it quickly dissociates to form difluoroacetate ions.

Dichloroacetic Acid (DCA) , also known as bichloroacetic acid (BCA), is a highly corrosive acid with the chemical formula C 2 H 2 Cl 2 O 2 . While it is used in personal care items and disinfectants, it is a known carcinogen.  Despite that, research shows that it may be a plausible treatment for certain cancers.

Trifluoroacetic Acid (TFA) is a synthetic organofluorine acid with the chemical formula C 2 HF 3 O 2 . It is corrosive and toxic to aquatic life and mammals, causing severe irritation and burns to skin, eyes, and the respiratory tract. Not only that, TFA is also highly mobile and persistent, leading to high retention of it in soil and water. Determination of it’s threat level on the environmental and health levels are still ongoing.

Trichloroacetic Acid (TCA) , also known as trichloroethanoic acid, is an analogue of acetic acid with the chemical formula C 2 H Cl 3 O 2 . It is often used as a skin peeling treatment to exfoliate damaged skin and encourage collagen production. In laboratory research, it is used for precipitating proteins and to extract and prepare standards for ascorbic acid (Vitamin C) assays.
