Glutaraldehyde is an organic compound with the formula CH2(CH2CHO)2. A pungent colorless oily liquid, glutaraldehyde is used to disinfect medical and dental equipment. It is also used for industrial water treatment and as a preservative. It is mainly available as an aqueous solution, and in these solutions the aldehyde groups are hydrated.
It is colorless or yellowish bright liquid with slight irritating odor; soluble in water, ether and ethanol.
It is active, can be easily polymerized and oxidized, and it is an excellent cross-linking agent for protein.
It also has excellent sterilizing properties.
It is a liquid intermediate, and can be in industrial water treatment, biocides, leather tanning, etc.
be used for system disinfection and as a preservative for long term storage
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.
It is widely used for oil production, medical care, bio-chemical, leather treatment, tanning agents, protein cross-linking agent; in the preparation of heterocyclic compounds; also used for plastics, adhesives, fuels, perfumes, textile, paper making, printing; corrosion prevention of instruments and cosmetics etc. It is widely used for oil production, medical care, bio-chemical, leather treatment, tanning agents, protein cross-linking agent; in the preparation of heterocyclic compounds; also used for plastics, adhesives, fuels, perfumes, textile, paper making, printing; corrosion prevention of instruments and cosmetics etc
4. Storage / transportion
Glutaraldehyde 50% has a shelf life of 12 months in unopened, original containers and kept below 25ºC. Ensure thorough ventilation of stores and work areas. Avoid aerosol formation and keep under inert gas.
