In de toepassingen van TAE buffer komt de rol van glazurige azijnzuur ook naar voren in de interactie met andere componenten in de oplossing. Triëthylamine (TEA) is een ander belangrijk bestanddeel van TAE buffer, en samen met azijnzuur creëert het een synergistische effect dat de algehele prestaties van de buffer verbetert. Dit leidt tot een efficiënte scheiding van DNA-fragmenten, wat van onschatbare waarde is voor genotypering, cloning en andere moleculaire biologie technieken.

Glacial acetic acid is also employed as a reagent in titrations, especially acid-base titrations. It serves as a weak acid and can be used to determine the concentration of basic substances in a solution. Through titration, chemists can analyze and quantify the amount of an unknown base by neutralizing it with a measured amount of glacial acetic acid. The endpoint of such titrations is crucial for determining various chemical properties and concentrations, making it an indispensable tool in quantitative analysis.

The unique properties of glacial acetic acid are a result of its molecular structure. The molecule comprises a carboxylic acid group (-COOH), which is responsible for its acidic behavior. At higher concentrations, glacial acetic acid does not dissociate completely but maintains a significant number of undissociated molecules, primarily due to its high viscosity and hydrogen bonding. This behavior differs considerably from diluted acetic acid, commonly found in household vinegar, where it is present in a solution with a much lower concentration of acetic acid.
