Tan powder. Soluble in alkaline solutions and organic bases.
[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]

Poison by intraperitoneal route.Experimental reproductive effects. When heated todecomposition it emits toxic fumes of NOx.
