Safety Data Sheet for Fisher Scientific Glacial Acetic Acid Essential Information and Handling Guide

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.

The main difference between these two forms of acetic acid lies in their water content and the consequent influence on their chemical behavior. Anhydrous acetic acid is more reactive due to its purity and is often employed in chemical synthesis where the presence of water could lead to unwanted side reactions. It serves as a solvent in polyvinyl acetate manufacturing and as a precursor in the production of various chemical compounds such as acetate esters, anhydrides, and even pharmaceuticals.

The applications of glacial acetic acid and diluted acetic acid vary significantly due to their differing properties. Glacial acetic acid is used primarily in industrial settings. It serves as an important chemical reagent and is widely employed in the production of various chemicals, such as acetate esters, acetic anhydride, and synthetic fibers like rayon. Its high purity level makes it ideal for manufacturing processes that require concentrated acids.
