:o-Tolidine
Description:
o-Tolidine, also known as 3,3'-dimethylbenzidine, is an organic compound with the chemical formula C14H16N2. It is characterized by its structure, which features two amino groups attached to a biphenyl framework, specifically at the ortho positions relative to each other. This compound appears as a yellow to orange crystalline solid and is soluble in organic solvents but has limited solubility in water. o-Tolidine is primarily used in the production of dyes and pigments, particularly in the textile and paper industries. However, it is important to note that o-tolidine is considered hazardous; it is a potential carcinogen and can pose health risks upon exposure. Safety precautions are essential when handling this substance, including the use of personal protective equipment and proper ventilation. Additionally, due to its toxicological profile, o-tolidine is subject to regulatory controls in many regions, emphasizing the need for careful management in industrial applications.

CAS:Controlled Product<p>o-Tolidine is an organic compound that is used in analytical chemistry as a reagent for the detection of amines. It reacts with amines to form an intensely coloured compound, which can be detected by a fluorescence detector. o-Tolidine has been shown to have a high toxicity in rats and humans, with no known antidote or treatment. The mechanism of this reaction is not yet fully understood, but it is believed to involve an acid-base reaction between the o-tolidine molecule and the amine at pH 2.5, followed by protonation of the o-tolidine molecule.</p>Formula:C14H16N2Purity:Min. 95%Molecular weight:212.29 g/molEPA Method 8270 Benzidines Mixture 2000 µg/mL in Methanol
