Description
Curator's Comment: description was created based on several sources, including https://www.nap.edu/read/13142/chapter/6 | https://www.drugs.com/pro/formaldehyde-liquid.html

Formaldehyde is a naturally occurring organic compound, and an important industrial precursor to many other materials and organic compounds. Formaldehyde solution (formalin) is used as a disinfectant. Formaldehyde vapors are toxic, upon entry formaldehyde reacts readily with macromolecules, including DNA to form DNA-protein and DNA-DNA cross-links.

Originator

Curator's Comment: Formaldehyde was first reported in 1859 by the Russian chemist Aleksandr Butlerov

Sample Use Guides

Formaldehyde 10% solution is applied topically once a day to affected areas.
Route of Administration: Topical
In Vitro Use Guide
Human lymphoblasts were exposed in vitro to various concentrations of formaldehyde (HCHO) in single and multiple treatment regimens to determine relative mutagenic efficiency. HCHO treatment resulted in a significant nonlinear increase in DNA-protein crosslinks at concentrations greater than 50 uM X 2 h, which correlated with the onset of significant toxicity in this cell line.
