Furthermore, glacial acetic acid plays a critical role in organic synthesis. It is used as a solvent in many reactions and helps in the production of acetate esters and other derivatives that are important in pharmaceuticals, agrochemicals, and even food additives. In addition to its industrial significance, glacial acetic acid is essential in laboratories for a variety of applications including titrations and chemical analyses.

100%酢酸（純酢酸）は、化学式CH₃COOHを持つ有機化合物で、透明で強い刺激臭を持つ液体です。その沸点は118.1℃であり、高い揮発性を持っています。酢酸は常温では液体の状態ですが、冷却すると固体の氷酢酸になることがあります。純度の高い酢酸はさまざまな産業や研究分野で広く利用されています。

In der Lebensmittelindustrie wird Essigsäure in verdünnter Form als Konservierungsmittel verwendet. Die antibakteriellen Eigenschaften wirken dem Wachstum von Mikroorganismen entgegen und verlängern so die Haltbarkeit von Lebensmitteln.

The word glacial derives from the Latin word “glacies,” which means ice. In the case of glacial acetic acid, the name is a reference to its ability to form solid crystalline structures resembling ice at low temperatures. When cooled, pure acetic acid solidifies and looks similar to ice, hence the use of the term glacial to describe it. This characteristic is not just a semantic curiosity; it signifies that glacial acetic acid has a high purity level and a distinct set of physical properties compared to diluted acetic acid found in household vinegar.
