However, the hazards associated with glacial acetic acid cannot be overlooked. Exposure to this chemical can lead to severe health issues, including irritation of the skin, eyes, and respiratory system. Inhalation of vapors can cause headaches, nausea, and in extreme cases, lung damage. Thus, laboratory and industrial personnel are expected to wear appropriate personal protective equipment (PPE), such as gloves and goggles, to minimize the risk of exposure.

Glacial acetic acid, also known as ethanoic acid, is a colorless, hygroscopic liquid with the chemical formula CH₃COOH. It is the most concentrated form of acetic acid, containing approximately 99-100% acetic acid content. Unlike diluted acetic acid, which is commonly found in vinegar, glacial acetic acid is a potent chemical compound that has unique properties, varied applications, and specific safety considerations.

One of the primary reasons researchers choose TAE buffer is its buffering capacity, which is influenced by the concentration of acetate ions. Glacial acetic acid serves to provide a robust source of acetate when it is dissolved with Tris and EDTA. The chemical equilibrium between the acetic acid and its anion (acetate) allows TAE buffer to maintain a pH of around 8.0 to 8.5, making it suitable for many applications in nucleic acid manipulation. This pH range is particularly compatible with various enzymes used in molecular cloning and DNA amplification techniques.
