Description

Formaldehyde is a 37% (saturated) solution stabilized with 10% methanol to limit oxidation and the degree of polymerization. Historically used as an embaliming agent due to its ability to crosslink primary amino groups in proteins through a methylene linkage; however, due to its extremely toxic nature it tends to be avoided. Formaldehyde is also used in numerous industrial applications and organic syntheses; some concern has been raised about the harmful exposure generated when used, or released from products containing it. Research suggests that exposure to Formaldehyde may cause respiratory irritation and an increase in the occurence of myeloid leukemia.
