glutaraldéhydes

Glutaraldehyde is a chemical compound with the formula CH2(CH)2CHO)2. It is a dialdehyde, meaning it has two aldehyde functional groups. It typically exists as an aqueous solution, often around 2% concentration. Glutaraldehyde is a colorless, oily liquid with a distinctive, pungent odor. It is highly reactive and is known for its biocidal properties.

Due to its ability to cross-link proteins and other organic molecules, glutaraldehyde is widely used as a sterilant and disinfectant, particularly for medical and dental equipment that cannot withstand heat sterilization. It is effective against a broad spectrum of microorganisms, including bacteria, viruses, fungi, and spores. Its effectiveness comes from its ability to alkylate proteins, disrupting cellular functions and leading to cell death.

However, glutaraldehyde is also a known irritant to the skin, eyes, and respiratory tract. Exposure can cause allergic reactions, sensitization, and respiratory problems. Proper handling procedures, including adequate ventilation and personal protective equipment, are essential when working with glutaraldehyde. It is also used in some industrial applications, such as in water treatment and as a component in some photographic developers.
