In enzymology, a formaldehyde dehydrogenase (EC 1.2.1.46) is an enzyme that catalyzes the chemical reaction formaldehyde + NAD + + H 2 O ⇌ {\displaystyle \rightleftharpoons } formate + NADH + H + The 3 substrates of this enzyme are formaldehyde , NAD + , and H 2 O , whereas its 3 products are formate , NADH , and H + .
Under anaerobic condition and without tetrahydrofolate, however, a free formaldehyde is formed after the N-demethylation of sarcosine. [12] The reaction with 1 mole of sarcosine and 1 mole of FAD, under this condition, yields 1 mole of glycine and 1 mole of formaldehyde (See figure 2 for mechanism). [9]
Formaldehyde is dangerous to human health. [8] [9] In 2011, the US National Toxicology Program described formaldehyde as "known to be a human carcinogen". [10] [11] [12] The danger of formaldehyde is a major reason for the development of formaldehyde releasers which release formaldehyde slowly at lower levels. [13]
Formaldehyde (/ f ɔːr ˈ m æ l d ɪ h aɪ d / ⓘ for-MAL-di-hide, US also / f ə r-/ ⓘ fər-) (systematic name methanal) is an organic compound with the chemical formula CH 2 O and structure H−CHO, more precisely H 2 C=O.
A lower molar ratio of formaldehyde decreases the emission of free formaldehyde from UF products. There is a significant decrease in formaldehyde emissions from UF-based particleboard from F/U molar ratio of 2.0 to 1.0. The German standard for UF resins require the F/U molar ratio to be below 1.2. The U.S. NPA standard is an F/U molar ratio ...
Diazolidinyl urea acts as a formaldehyde releaser. It is used in many cosmetics, skin care products, shampoos and conditioners, as well as a wide range of products including bubble baths, baby wipes and household detergents. Diazolidinyl urea is found in the commercially available preservative Germaben.

In organic chemistry, the Mannich reaction is a three-component organic reaction that involves the amino alkylation of an acidic proton next to a carbonyl (C=O) functional group by formaldehyde (H−CHO) and a primary or secondary amine (−NH 2) or ammonia (NH 3). [1] The final product is a β-amino-carbonyl compound also known as a Mannich base.
