Formaldehyde is an aldehyde resulting from the formal oxidation of methanol. It has a role as a disinfectant, a carcinogenic agent, an allergen, a mouse metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite, an EC 3.5.1.4 (amidase) inhibitor and an environmental contaminant. Solids containing varying amounts of formaldehyde, probably as paraformaldehyde (polymers of formula HO(CH2O)xH where x averages about 30). A hazard to the environment. Immediate steps should be taken to limit spread to the environment.
