Widely used as a fixative in electron microscopy to preserve cellular structures with high fidelity. It stabilizes proteins and other biomolecules by forming cross-links, maintaining the natural architecture of tissues for detailed imaging. Commonly applied in biological and medical research for sample preparation. Also used in histology and pathology labs for tissue preservation prior to embedding and sectioning. Its strong biocidal properties make it effective for disinfecting medical and laboratory equipment, particularly heat-sensitive instruments. Used in water treatment systems to control microbial growth. Employed in the preservation of vaccines and in some dental applications for its antimicrobial action.
