Chemical Properties
Tan powder. Soluble in alkaline solutions and organic bases.
Uses
Organic synthesis.
Uses
1,2,3-Benzotriazin-4(3H)one is used to prepare 3-methoxymethyl-3H-benzo[d][1,2,3]triazin-4-one by reacting with dimethoxymethane. Further, it undergoes thermal condensation with alfa-amino acids to give 3H-1,4-benzodiazepin-(1H,4H)-2,5-diones. In addition to this, it is employed as a reagent to synthesize 1,2,3-bBenzotriazin-4-one-arylpiperazine derivatives.
Uses
1,2,3-Benzotriazin-4(3H)-one is part of a group of compounds that exhibit antimicrobial activity. 1,2,3-Benzotriazin-4(3H)-one is also used as a reagent to synthesize 1,2,3-Benzotriazin-4-one-arylpiperazine derivatives, compounds that act as Serotonin (HCl: S274980) receptor ligands.
Definition
Bicyclic.
General Description
1,2,3-Benzotriazin-4(3H)-one is an 1,2,3-benzotriazine derivative. 1,2,3-Benzotriazin-4(3H)-one undergoes thermal condensation with α-amino acids to yield 3H-1,4-benzodiazepin-(1H,4H)-2,5-diones. 1,2,3-benzotriazin-4(3H)-one on thermolysis yields quinazolino[3,2-c][1,2,3]benzotriazin-8-one.
Safety Profile
