What is Acetic Acid?
Acetic acid, commonly known as vinegar acid, is a simple carboxylic acid with the chemical formula CH₃COOH. It is characterized by its strong, pungent smell and is most commonly recognized as the key component of vinegar. Beyond its use in culinary applications, acetic acid is a fundamental building block in the production of a wide range of chemicals, including acetates, plastics, and synthetic fibers. It also plays an important role in metabolism within living organisms as part of the citric acid cycle.
Due to its versatile nature, acetic acid analysis is a critical tool in multiple industries, including:
- Biochemical research – Studying metabolic pathways and enzyme activity.
- Food industry – Ensuring the quality of vinegar and fermented products.
- Pharmaceuticals – Determining the concentration in drug formulations.
- Environmental monitoring – Testing for acetic acid in water and waste samples.
