용도

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.

참고

Incompatible with strong oxidizing agents, strong acid and bases.
