3,3′-Diaminobenzidine (DAB) is an organic compound with the formula (C 6 H 3 (NH 2) 2) 2. This derivative of benzidine is a precursor to polybenzimidazole, which forms fibers that are renowned for their chemical and thermal stability. [1] As its water-soluble tetrahydrochloride, DAB has been used in immunohistochemical staining of nucleic ...
para-Dimethylaminobenzaldehyde is an organic compound containing amine and aldehyde moieties which is used in Ehrlich's reagent and Kovac's reagent to test for indoles. The carbonyl group typically reacts with the electron rich 2-position of the indole but may also react at the C-3 or N-1 positions. [2] It may also be used for determination of ...
The metabolite N-(3-hydroxypentyl) JWH-018 was found to have toxic effects that its parent compound does not. [77] Some metabolites even appear to be cannabinoid antagonists. [78] Lastly, they may contain unwanted substances, be mislabeled, or contain different doses than advertised (in one analysis, a difference of one log unit was found). [77]
DABCO (1,4-diazabicyclo[2.2.2]octane), also known as triethylenediamine or TEDA, is a bicyclic organic compound with the formula N 2 (C 2 H 4) 3.This colorless solid is a highly nucleophilic tertiary amine base, which is used as a catalyst and reagent in polymerization and organic synthesis.

Shows the oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) to 3,3',5,5'-tetramethylbenzidine diimine. The resulting one-electron oxidation product is a diimine-diamine complex, which causes the solution to take on a blue colour, [2] and this colour change can be read on a spectrophotometer at the wavelengths of 370 and 650 nm.
Putrescine is an organic compound with the formula (CH 2) 4 (NH 2) 2. It is a colorless solid that melts near room temperature. It is classified as a diamine. [3] Together with cadaverine, it is largely responsible for the foul odor of putrefying flesh, but also contributes to other unpleasant odors.
