Glutaraldehyde is an organic compound with the formula (CH₂)₃(CHO)₂. The molecule consists of a five carbon chain doubly terminated with formyl (CHO) groups. It is usually used as a solution in water, and such solutions exists as a collection of hydrates, cyclic derivatives, and condensation products, several of which interconvert. Because the molecule has two carbonyl group that are reactive to primary amine groups (even as its hydrates), it can function as a crosslinking agent for any substance with primary amine groups and develop imine connected links. Crosslinking rigidifies and deactivates many biological functions, so in this way, glutaraldehyde solutions are used as biocides and as fixative. It is sold under the brandnames Cidex and Glutaral. As a disinfectant, it is used to sterilize surgical instruments.
