Glutraldehyde
Glutaraldehyde is an organic compound.
Glutaraldehyde is used to disinfect medical, dental equipment,
industrial water treatment and as a chemical preservative.
Glutaraldehyde is a chemical frequently used as
a disinfectant and sterilizing agent against bacteria and viruses
(2% solution), an embalming fluid and tissue fixative, a component
of leather tanning solutions, and an intermediate in the production
of certain sealants, resins, dyes, and electrical products.
