Acetic Acid (CH₃COOH) is a colorless, corrosive liquid with a pungent, vinegar-like odor. It is a widely used organic acid in both industrial and food-grade applications. Commonly available in concentrations like glacial (≥99%) or diluted solutions, it serves as a key raw material in the production of vinyl acetate monomer, acetic anhydride, esters, and various chemical intermediates. It is also used in textile printing, food preservation (as E260), pharmaceuticals, and cleaning agents. Known for its strong acidity, high solubility in water, and reactivity, acetic acid is both versatile and economically important.
