What is o-Tolyl biguanide?
Chemical properties
White to off-white powder. Combustible. o-Tolylbiguanide (OTBG) [93-69-6], C9H13N5, Mr 191.23, mp 144 ℃, is used as a vulcanization accelerator in the same manner as the guanidines DPG and DOTG. An important use is in the preparation of consumer articles that come in contact with food and drinking water (Recommendation XXI of the German Federal Department of Health). o-Tolylbiguanide is also employed as a curing agent with moderate reactivity for color-stable, highly glossy or transparent epoxy resin powder coatings.
The Uses of o-Tolyl biguanide
Antioxidant for soaps produced from animal or vegetable oil.
The Uses of o-Tolyl biguanide
1-(o-Tolyl)biguanide was used as a ligand in the synthesis of new vanadyl complexes with the formula [VOL2].xH2O (HL=1-(o-tolyl)biguanide, x=0.5).
