  • In 1872 the German chemist Adolf von Baeyer condensed trifunctional phenol and difunctional formaldehyde, and in subsequent decades Baeyer's student Werner Kleeberg and other chemists investigated the products, but they failed to pursue the reaction because they were unable to crystallize and characterize the amorphous resinous products.

  • More related to its alcohol dehydrogenase activity, GSNOR null mice show a 30% reduction in the LD50 for formaldehyde and a decreased capacity to metabolize retinol, although it is clear from these studies that other pathways exist for the metabolism of these compounds. (wikipedia.org)
  • organic
  • Formaldehyde was the first polyatomic organic molecule detected in the interstellar medium. (wikipedia.org)
  • Formaldehyde was the first polyatomic organic molecule detected in the interstellar medium and since its initial detection has been observed in many regions of the galaxy. (wikipedia.org)
  • Formaldehyde is believed to be the primary precursor for most of the complex organic material in the interstellar medium, including amino acids. (wikipedia.org)
  • adhesives
  • Formaldehyde may be contained in wood-based materials, e.g. for construction and furniture, as a constituent of adhesives, and is considered to be carcinogenic. (umweltbundesamt.de)
  • The Deutsches Institut für Bautechnik (DIBt) has required corresponding tests for the approval of flooring, bottom application layers, parquet varnishes, surface coatings for flooring, adhesives, and wall coverings, which also address the outgassing of formaldehyde. (umweltbundesamt.de)
  • CH3OH
  • Unlike OH, H2O, and CH3OH, only five galactic star forming regions have associated formaldehyde maser emission, which has only been observed through the 110 → 111 transition. (wikipedia.org)

  • Although the total number of NPL sites evaluated for this substance is not known, the possibility exists that the number of sites at which formaldehyde is found may increase in the future as more sites are evaluated. (cdc.gov)
  • emissions
  • In 1985, HUD began providing guidelines for formaldehyde emissions in manufactured homes. (ehow.com)
  • The use of pressed wood and other materials that contained formaldehyde were still permitted but the emissions that were given off by the materials were required to meet certain specifications. (ehow.com)
  • water
  • When dissolved in water, formaldehyde is used as a preservant and disinfectant. (reference.com)
  • Because of its biocidal properties when dissolved in water, formaldehyde is often used for disinfecting surfaces and equipment in biological and medical settings. (reference.com)
  • It's even harder to imagine that the bras were inadvertently contacted with formaldehyde -- that's because it quickly dissipates in air, water and sunlight. (go.com)
