WCl5
metal· WCl5
WCl₅ (tungsten pentachloride) is a transition metal halide compound consisting of tungsten in the +5 oxidation state bonded to five chlorine atoms. It is primarily used as a precursor and catalyst in chemical synthesis, materials processing, and thin-film deposition rather than as a structural engineering material. The compound is notable in organometallic chemistry and CVD (chemical vapor deposition) processes for producing tungsten-containing coatings and films, and serves as a starting material for synthesizing tungsten oxides and other tungsten compounds used in catalysis and electronics applications.

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.
