A process for producing 1,2,4-triazol-5-one comprises reacting a semicarbazide compound with a formic acid compound formylating agent in the presence of a catalytic amount of a sulfur-oxygen containing acid. The process is able to produce 1,2,4-triazol-5-one from semicarbazide hydrochloride having significantly lower concentrations of chloride ion, which is advantageous, for example, in the production of 3-nitro-1,2,4-triazol-5-one as an explosive used in castable explosive compositions.
