The COVID-19 pandemic has had a long-lasting impact on supply chains across many industries. Disruptions in transportation, labor shortages, and factory shutdowns led to a decrease in production capabilities and an increase in costs. For instance, the production of glacial acetic acid primarily depends on methanol and carbon monoxide, whose availability can be affected by fluctuations in oil prices and the geopolitical climate. If these raw materials become expensive or scarce, manufacturers are likely to pass these costs on to consumers, resulting in higher prices.

In addition to providing pH adjustment, glacial acetic acid acts as a molecular weight modifier. During the electrophoresis run, nucleic acids and proteins migrate through the porous agarose gel matrix. The properties of the gel, including its porosity and the ionic strength of the running buffer, can be altered using glacial acetic acid. These modifications allow for a more controlled separation based on the specific size of the molecules being examined. For instance, by optimizing acetic acid concentration, researchers can fine-tune the resolution of bands in the gel, enabling better visualization and differentiation of molecules that are closely sized.

Furthermore, glacial acetic acid has significant applications in the laboratory. Its high purity level makes it an ideal solvent and reagent for various chemical reactions. It is commonly used in analytical chemistry, where precise reactions are required. The ability to act as a solvent for both polar and nonpolar substances expands its utility in a variety of research and development scenarios.

One of the defining characteristics of glacial acetic acid is that it has a freezing point of about 16.6 degrees Celsius (62 degrees Fahrenheit). Below this temperature, it solidifies into a crystalline form that resembles ice, which is where the term glacial comes from. The clear liquid that remains above this freezing point is known for its pungent, vinegar-like odor, which is characteristic of all acetic acid compounds.
