[Description]

5-methyl-1H-tetrazole (MTZ) is a tetrazolium derivative. MTZ can be used as a starting material for the synthesis of novel energetic salts (including cationic and anionic salts, such as perchlorate, nitrate, guanidine salt, etc.)[1]. It can also form eutectic compounds with 5-Aminotetrazole to improve the combustion performance of pyrotechnic fuels and enhance their moisture resistance[2].
[Safety]

5-methyl-1H-tetrazole is a flammable solid. This substance is irritating to humans. Contact may cause skin irritation and severe eye irritation. Inhalation may cause respiratory tract irritation.
