1.Product description
Name: Glutaraldehyde 50%
CAS NO. 111-30-8
Appearance: colorless or yellowish clear and bright liquid
2.characteristics and applications
Glutaraldehyde is colorless or yellowish clear and bright liquid with slight irritating smell, and can be dissolved in organic dissolvent such as water, ether and ethanol.
In water solution, Glutaraldehyde doesn't exist much in free state; instead, Glutaraldehyde makes appearance as hydrates with different forms.and most of them are hydrates with annular structure.
Glutaraldehyde is reactive in property, and liable to polymerize and oxidize, which will react with compounds containing active oxygen and nitrogen. The reaction of the product with protein is mainly carried out between the carbonyl group of the former and the amino group of the latter. Among the known aldehydes, the product is one of the best cross-linking agents for proteins.
Glutaraldehyde has a small influence on the activity of enzyme, and most of enzymes can be fixed under controlled condition, to cross-link without losing their activity. Contrbuting to its outstanding characteristics, the product has drawn special concern from people and been put at broad application.

Sodium metabisulfite is white or yellow crystalline powder or small crystal, with a strong SO2 odor, soluble in water, the aqueous solution is acidic, when contacted with strong acid, SO2 is released to form corresponding salts, and it is oxidized to Na2S2O6 when placed in the air for a long time. Therefore, the product cannot be stored for a long time. Above 150 degrees Celsius, SO2 is decomposed.
