Used as a precursor in sol-gel processes for depositing molybdenum oxide thin films, which are applied in electrochromic devices and gas sensors. It serves as a catalyst or catalyst support in organic synthesis and petrochemical refining due to molybdenum’s redox activity. Also employed in the preparation of molybdenum-containing nanomaterials and mixed-metal oxides for electronic and optical applications. Its reactivity with moisture and alcohols makes it suitable for in situ generation of active molybdenum species in chemical vapor deposition (CVD) and atomic layer deposition (ALD) techniques.
