Used primarily as a fixative in electron microscopy to preserve the fine structural details of cells and tissues. It stabilizes proteins and other cellular components by cross-linking amino groups, maintaining structural integrity during sample processing. Commonly used in biological and medical research for preparing specimens for both transmission and scanning electron microscopy. Also utilized in histology labs for tissue preservation prior to embedding and sectioning. Due to its strong antimicrobial properties, it serves as a disinfectant in medical and dental equipment sterilization.
