glutaaraldehüüd

Glutaaraldehüüd is a chemical compound with the formula C5H8O2. It is a dialdehyde, meaning it contains two aldehyde functional groups. Glutaaraldehüüd is a colorless, oily liquid with a pungent odor. It is soluble in water and alcohol. In its pure form, it is known as glutaraldehyde. It exists as a hydrate in aqueous solutions, primarily as a cyclic hemiacetal.

Glutaaraldehüüd is widely used as a sterilizing and disinfecting agent. Its effectiveness stems from its ability to cross-link proteins and nucleic acids, which inactivates microorganisms. It is particularly effective against bacteria, viruses, fungi, and spores. Due to its biocidal properties, it finds application in healthcare settings for sterilizing medical and dental equipment that cannot withstand high temperatures. It is also used in industrial applications for water treatment and as a preservative.

Despite its efficacy, glutaaraldehüüd is a strong irritant and sensitizer. Exposure can cause irritation to the eyes, skin, and respiratory tract. Prolonged or repeated contact can lead to allergic reactions. Therefore, proper handling procedures, including the use of personal protective equipment and adequate ventilation, are essential when working with this chemical. It is typically supplied as an aqueous solution, often with a pH between 4 and 7.
