Another advantage of using glacial acetic acid in agarose gel electrophoresis is its compatibility with various biological samples. Acetic acid is a relatively mild reagent that does not significantly interfere with the integrity of nucleic acids. Moreover, after the electrophoresis run, gels containing glacial acetic acid can be stained with ethidium bromide or other nucleic acid stains, allowing for visual detection under UV light. The presence of acetic acid aids in ensuring even distribution of these stains throughout the gel, resulting in clearer and more quantitative bands.

Eine weitere Anwendung ist in der Lebensmittelindustrie, wo 2%ige gefrierende Essigsäure als Konservierungsmittel genutzt wird. Essigsäure hat antimikrobielle Eigenschaften, die das Wachstum von Schimmel und Bakterien in Lebensmitteln verhindern können, was zu einer längeren Haltbarkeit führt. So finden sich 2%ige Lösungen in verschiedenen Marinaden und Konserven.

While both glacial acetic acid and ethanol are important industrial chemicals, they require careful handling. Glacial acetic acid is corrosive and can cause skin burns, while its vapors can irritate the respiratory system. Therefore, it is essential to use appropriate safety measures when working with these substances, including the use of personal protective equipment (PPE) and operating in well-ventilated areas.
