Acetic acid, also known as ethanoic acid, is a colorless liquid organic compound with the chemical formula CH3COOH. When it is in its purest form, without water content, it is referred to as “glacial acetic acid.” Acetic acid is a vital chemical with a wide range of industrial, laboratory, and household applications.

Glacial acetic acid is commonly used as a solvent and chemical reagent. It is a key component in the production of various chemicals, including acetic anhydride, which is used in the manufacture of cellulose acetate and other products. In the food industry, it is utilized as an acidity regulator and preservative, and it is a fundamental ingredient in the production of vinegar.

Acetic acid is also used in laboratories for various analytical and synthetic purposes. In household settings, it is found in vinegar and cleaning products. While acetic acid is generally safe when used properly, it is a corrosive substance and should be handled with care, particularly in concentrated forms.
