1. Chemical Synthesis One of the most significant applications of 99.5% acetic acid is in the production of various chemicals. It is a key ingredient in the manufacture of acetic anhydride and acetate esters, which are used as solvents, plasticizers, and in the production of synthetic fibers. The high purity of glacial acetic acid is essential for producing chemical compounds that require precision and quality.

In gel electrophoresis, DNA fragments are separated based on their size. The presence of acetate ions from glacial acetic acid aids in this process. Acetate ions facilitate the conductivity of the buffer, helping to maintain a uniform electric field across the gel. This is vital for the consistent migration of DNA fragments and sharp resolution of bands. Any irregularity in the buffer’s ionic strength can lead to band distortion or poor resolution, making the proper concentration of glacial acetic acid critical to successful nucleic acid analysis.

Formic acid, HCOOH, is the simplest carboxylic acid, consisting of a hydrogen atom bonded to a carbonyl group (C=O) and a hydroxyl group (OH). Its molecular structure makes it highly reactive, a characteristic that is both advantageous and challenging in its usage. In its glacial form, it has a high concentration, usually around 98-100%, which amplifies its acidic properties.
