Formaldehyde is one of the main disinfectants recommended for destroying anthrax. [55] Formaldehyde is also approved for use in the manufacture of animal feeds in the US. It is an antimicrobial agent used to maintain complete animal feeds or feed ingredients Salmonella negative for up to 21 days. [56]
In enzymology, a mycothiol-dependent formaldehyde dehydrogenase (EC 1.1.1.306) is an enzyme that catalyzes the chemical reaction formaldehyde + mycothiol + NAD + ⇌ {\displaystyle \rightleftharpoons } S-formylmycothiol + NADH + 2 H +
Sensitization to formaldehyde has been decreasing since 1980 due in part to the replacement of formaldehyde by these formaldehyde releasers. [2] As of 2009, frequency of sensitization to formaldehyde is stable at 2–3% in Europe. [2] It might be as high as 9% in the USA. [2] [13]
In the earliest forms of denaturation mapping, DNA was denatured by heating in presence of formaldehyde [1] or glyoxal [3] and visualized using electron microscopy. Dyes that selectively bind to double stranded DNA like ethidium bromide could be used to monitor the extent of denaturation.
In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation, radiation, or heat.

Quaternium-15 is an allergen, and can cause dermatitis. [6] Many of those with an allergy to quaternium-15 are also allergic to formaldehyde. At low pHs, it would be expected to release significant amounts of formaldehyde due to acid hydrolysis via the Delepine reaction.
The RNA samples are most commonly separated on agarose gels containing formaldehyde as a denaturing agent for the RNA to limit secondary structure. [ 11 ] [ 12 ] The gels can be stained with ethidium bromide (EtBr) and viewed under UV light to observe the quality and quantity of RNA before blotting. [ 11 ]
It is the oxime of formaldehyde. A colorless liquid, the pure compound tends to polymerize into a cyclic trimer. Aqueous solutions are stable as is the formaldoxime hydrochloride ([H 2 C=N(−H)(−OH)] + Cl −). It is a reagent in organic synthesis for the conversion of aryl diazonium salts to aryl aldehydes. [1]
