Glutaraldehyde is a colorless or yellowish clear liquid with a slightly irritating special odor, which is soluble in water and organic solvents such as ether . There are not many free forms in aqueous solutions, with a large number of different forms of hydrates, while most of them are in the form of cyclic hydrates. Glutaraldehyde has active properties and is prone to polymerization and oxidation. It reacts with compounds containing active oxygen and nitrogen. The reaction with proteins mainly involves the reaction of carbonyl groups with amino groups in protein molecules. Among known aldehydes, glutaraldehyde is the best protein crosslinking agent. Glutaraldehyde has excellent bactericidal properties. Glutaraldehyde has little effect on the activity of this enzyme, and most enzymes can be immobilized, cross-linked, and not inactivated under controlled conditions. Due to its numerous excellent properties, glutaraldehyde has attracted great attention and has been widely used.
Highly flammable. Slightly soluble in water; Soluble in ethanol and ether. When exposed to oxygen, ethers often form unstable peroxides. Ethyl, isobutyl, ethyl tert butyl, and ethyl tert amyl ethers are particularly dangerous in this regard. Sometimes it can be observed that ether peroxides deposit in the form of transparent crystal Chemicalbooks on containers or along the liquid surface. Colorless liquid with chemical properties. Melting point -92 , boiling point 93.8 , relative density 0.7888 (20/4 ), refractive index 1.4026, flash point -9. Easily soluble in alcohols and ethers, slightly soluble in water.
