Due to the amino group bonded to the aromatic ring, the toluidines are weakly basic. The toluidines are poorly soluble in pure water but dissolve well in acidic water due to formation of ammonium salts, as usual for organic amines. ortho - and meta -toluidines are viscous liquids, but para -toluidine is a flaky solid.

Toluidina. La toulidina es un compuesto químico derivado del tolueno o metilbenceno, (C 6 H 5 CH 3 ), clasificable como un amino-compuesto, específicamente una amina aromática o aril-amina. Hay tres isomeros de la toluidina: la orto-toluidina (o-toluidina), la meta-toluidina (m-toluidina) y la para-toluidina (p-toluidina).
Toluidine blue (also known as tolonium chloride) is an acidophilic metachromatic dye that selectively stains acidic tissue components (sulfates, carboxylates, and phosphate radicals). Toluidine blue (TB) has an affinity for nucleic acids, and therefore binds to nuclear material of tissues with a high DNA and RNA content.[ 2 ]

Toluidine blue is a basic thiazine metachromatic dye with high affinity for acidic tissue components, thereby staining tissues rich in DNA and RNA. It has found wide applications both as vital staining in living tissues and as a special stain owing to its metachromatic property. Toluidine blue has b ….
ortho -Toluidine is a constituent of tobacco smoke and it is excreted in larger amounts in the urine of smokers than of non-smokers ( Riedel et al ., 2006 ). ortho -Toluidine induced urinary bladder and mammary gland tumours in rats and liver tumours and haemangiosarcomas in mice.
