Uses
Biochemistry
Glutaraldehyde is used in biochemistry applications as an amine-reactive homobifunctional
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
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
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.
As a strong sterilant, glutaraldehyde is
Production and reactions
Production
Glutaraldehyde is produced industrially by the catalytic oxidation of
Reactions
Like other dialdehydes, (e.g.,
A number of mechanisms have been invoked to explain the biocidal and fixative properties of glutaraldehyde.
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]
