Structural reassignment of the alleged 6‐hydroxy‐1,2,4‐triazine‐3,5‐(2H,4H)dione

Abstract

The reaction of 6‐amino‐1,2,4‐triazine‐3,5‐(2H,4H)clione with sodium hydroxide or nitrous acid has been shown to give 5‐hydroxy‐1,2,4‐triazole‐3‐carboxylic acid instead of 6‐hydroxy‐1,2,4‐triazine‐3,5‐(2H,4H)dione as reported in the literature. The triazolecarboxylic acid was also obtained from the aminotriazine and hydrochloric acid.
