Product Description

Ammonium tetrathiomolybdate (ATTM), (NH4)2MoS4, is a dark red crystalline inorganic salt used as a precursor for molybdenum sulfide catalysts, coatings, and thin films. Its tetrathiomolybdate anion supplies molybdenum and sulfur within a single compound, supporting the preparation of MoS2 and related sulfide materials through controlled thermal processing. Applications include catalyst preparation for petrochemical processing, solution based deposition of molybdenum sulfide films, and synthesis of transition metal sulfide compounds.
