Used primarily in histopathology and anatomical laboratories to preserve biological tissues. It stabilizes proteins and nucleic acids by cross-linking, preventing autolysis and decay. Commonly used in preparing tissue samples for microscopic examination, ensuring structural integrity during processing, embedding, sectioning, and staining. Also utilized in preserving anatomical specimens in education and research. Due to its strong fixation properties, it is essential in diagnostic pathology for accurate tissue analysis. Requires careful handling due to toxicity and potential health hazards.
