Documented Uses

  • Has been detected in exhaust of internal combustion engines, in emissions from waste incineration and cook stoves, in brake lining and tire particles, and in trace amounts in garlic; [HSDB] Related compounds find uses in perfumes, pharmaceuticals, as dyestuff intermediates, and flavoring agents; [NTP]
  • Prepared by reacting nitropropane with o-xylyl bromide in the presence of sodium ethanoate.
  • p-Tolualdehyde was oxidized to p-toluic acid by resting cells of pseudomonas aeruginosa. Perillaldehyde dehydrogenase, isolated from soil pseudomonad, catalyzed the oxidn of m- & p-tolualdehyde but not o-tolualdehyde.
  • Aldehydes are readily oxidized to organic acids. Oxidation of aldehydes is catalyzed by aldehyde dehydrogenase, which has been found in the brain, erythrocytes, liver, kidney, heart, and placenta. /Aldehydes/
