Histology and Cell Biology Staining
Xylene is widely used as a clearing agent in tissue processing for histology. It effectively removes paraffin wax from tissue sections, making them permeable for staining procedures, thus aiding in microscopic examination.
Solvent Applications
As an effective organic solvent, Xylenes are employed in dissolving various substances, including resins, paints, and inks. It is also used as a diluent in formulations and for cleaning laboratory equipment.
Chemical Synthesis Intermediate
The isomeric mixture of Xylenes serves as a feedstock in the synthesis of other organic chemicals, such as terephthalic acid (used in PET production) and phthalic anhydride.
