Uses

Biochemistry

Glutaraldehyde is used in biochemistry applications as an amine-reactive homobifunctional

membrane lipids
.

Another application for treatment of proteins with glutaraldehyde is the inactivation of bacterial toxins to generate

Material Science

In material science glutaraldehyde application areas range from polymers to metals and biomaterials. Glutaraldehyde is commonly used as fixing agent before characterization of biomaterials for microscopy. Glutaraldehyde is a powerful crosslinking agent for many polymers containing primary amine groups.[citation needed]. Glutaraldehdye also can be used for an interlinking agent to improve the adhesion force between two polymeric coatings.[11] Glutaraldehyde is also used to protect against corrosion of undersea pipes.[12]

Medical

Clinical uses

Glutaraldehyde is used as a

surgical instruments and other areas.[3]

Dermatological uses

As a medication it is used to treat plantar warts.[4] For this purpose, a 10% w/v solution is used. It dries the skin, facilitating physical removal of the wart.[14]

Glutaraldehyde is also used in the treatment of

aluminum chloride. Glutaraldehyde solution is an effective agent to treat palmar and plantar hyperhidrosis as an alternative to tannic acid and formaldehyde.[15]

Other Uses

Aquaria

Glutaraldehyde diluted with water is often marketed as alternative to carbon dioxide gas injection for aquarium plants, but it lacks any characteristics that promote the growth of aquatic plants, and does not raise the CO2 concentration of water it is added to.

Safety

Side effects include skin irritation.

dialdehyde.[18] It works by a number of mechanisms.[17]

As a strong sterilant, glutaraldehyde is

carcinogenic activity,[20] However, some occupations that work with this chemical have an increased risk of some cancers.[20]

Production and reactions

Production

Glutaraldehyde is produced industrially by the catalytic oxidation of

Diels-Alder reaction of acrolein and vinyl ethers followed by hydrolysis.[23]

Reactions

Like other dialdehydes, (e.g.,

Michael reactions yielding alpha, beta-unsaturated poly-glutaraldehyde and related oligomers. This reaction occurs at alkaline pH values.[25]

A number of mechanisms have been invoked to explain the biocidal and fixative properties of glutaraldehyde.

crosslinker, which rigidifies macromolecular structures and shuts down their reactivity.[26]

Imine formation from a primary amines and the carbonyls of glutaraldehyde is the basis of its fixative and biocidal properties.

The aldehyde groups in glutaraldehyde are susceptible to formation of imines by reaction with the amines of lysine and nucleic acids. The derivatives from aldol condensation of pairs of glutaraldehyde also undergo imine formation.[25]
