Glutaraldehyde 25% in aqueous solution
Supplier: MP Biomedicals
Glutaraldehyde is also referred to as glutaral, 1,5-pentanedione, potentiated acid glutaraldehyde, sonacide, and glutardialdehyde. Pure monomeric glutaraldehyde has an absorbance peak at 280 nm and the main impurity, possibly a polymer, has an absorbance peak at 235 nm. Upon analysis, this product is 25-28% by titration and has an A235/A280 ratio of not more than 0,5. Monomeric glutaraldehyde may be purified from polymeric glutaraldehyde by treatment with charcoal (5% w/v) and subsequent filtration (3-4 times). Untreated glutaraldehyde has an absorption at 235 nm that is 5 times greater than that at 280 nm, whereas, after three washings the values are about equal. Glutaraldehyde is a bifunctional cross-linking reagent, reacting with NH2 groups to form Schiff's bases.
