  • Applications

    Glutaric dialdehyde (glutaraldehyde) solution, CAS 111-30-8, is widely applied as a high-level disinfectant and sterilant for medical, dental and endoscopic equipment; a tissue fixative in electron microscopy, pathology and immunology thanks to its rapid protein cross-linking that preserves ultrastructure; a water-treatment biocide for cooling towers, paper-pulp circuits, and oil & gas pipelines; a preservative in vaccines, cosmetics and hand-sanitizer formulations; a chrome-free leather tanning agent that enhances durability and flexibility; a chemical intermediate for pharmaceuticals, dyes, polymers and epoxy resins; a modifier and cross-linker for gelatin, collagen and starch to produce films, microcapsules and biomedical materials; an H₂S scavenger and microbial control agent in petroleum extraction and aquaculture; and a key reagent for enzyme immobilization and biosensor fabrication.
