· JVASP-85222· W2NCl8

W2NCl8 is a tungsten nitride chloride compound representing an advanced interstitial metal nitride in the tungsten-nitrogen-chlorine system. This material exists primarily in research and development contexts as a potential precursor or functional compound for high-performance coatings and ceramics rather than as a mainstream structural metal. The chlorine component suggests potential applications in chemical vapor deposition (CVD) processes or as a reactive intermediate for synthesizing tungsten nitride films, which are valued in the semiconductor, tool coating, and hard materials industries for their hardness and thermal stability.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
