5-Mercapto-1-methyltetrazole Chemical Properties,Uses,Production

Chemical Properties

White Solid


N-Methyl-5-tetrazolethiol (Cefoperazone EP Impurity C) is an impurity of Cefoperazone.


An impurity of Cefoperazone.


5-Mercapto-1-methyltetrazole may be employed as heterocyclic ligand to study the geometry and stereochemical activity of the lone pair at the lead atom in hemi- and holo-directed lead(II) complexes. It may be used in the chemical modification of submicron particles of mesoporous MSU-2 silica and SBA-15 mesoporous silica.

General Description

5-Mercapto-1-methyltetrazole is a heterocyclic thiol derivative. It forms dimeric or tetrameric complexes with trimethylgallium.

Safety Profile

Poison by intraperitoneal route. Experimental reproductive effects. When heated to decomposition it emits very toxic fumes of NOx and SOx.

Synthesis of 5-Mercapto-1-methyltetrazole from Methyl isothiocyanate
