What is toluidine used for?

What is toluidine used for?

o-Toluidine is a colorless to pale yellow liquid that turns dark on exposure to air or light. It is used in making textile dyes, rubber chemicals, pharmaceuticals, and pesticides.

What is the nature of P-toluidine?

ortho- and meta-toluidines are viscous liquids, but para-toluidine is a flaky solid. This difference is related to the fact that the p-toluidine molecules are more symmetrical. p-Toluidine can be obtained from reduction of p-nitrotoluene. p-Toluidine reacts with formaldehyde to form Tröger’s base.

Where is toluidine found?

ortho-Toluidine has also been detected in surface waters and industrial effluents (Shackelford & Keith, 1976; Neurath et al., 1977; EPA, 1984; NTP, 2004), in vegetables such as kale, celery and carrots, in the volatile aroma of black tea (Vitzthum et al., 1975; Neurath et al., 1977), and in breast milk (DeBruin et al..

What is the formula of P toluidine?

C7H9Np-toluidine / Formula

What is the function of Ortho toluidine in glucose test?

o-Toluidine, 6% (v/v) in glacial acetic acid, is used to determine glucose in biologic material after deproteinization with 3% (w/v) trichloracetic acid. A stable green color develops after heating at 100° for 10 min., and the absorbance is determined at 630 or 635 mµ.

How do you make an Orthotolidine solution?

Roake gives the following directions for preparing the reagent: “To 1 gram of o-tolidine add the calculated amount of hydro- chloric acid (“‘ about 236 c. c.”), stir well, diltute to about 500 c. c. and filter. The residue left on the filter will be found to be soluble in distilled water. Make up to 1 liter.”

What is principle of Orthotolidine method?

Principle. A solution of orthotoluidine in glacial acetic acid when treated with glucose produces a blue coloured product with an absorption maximum at about 640nm. The values obtained represent the true glucose level.

What is the formula of p-toluidine?

What is the structure of toluidine?

p-Toluidine
