· JVASP-99027· WSCl4

WSCl₄ (tungsten tetrachloride) is a transition metal halide compound that exists primarily as a research and industrial chemical intermediate rather than a structural or functional engineering material in its pure form. It is encountered in materials processing workflows—particularly in chemical vapor deposition (CVD), tungsten metallurgy, and specialty synthesis—where it serves as a tungsten source or precursor. Engineers and materials scientists select tungsten halides for applications requiring controlled tungsten incorporation, high-purity deposition, or as a reactant in synthesis routes where chloride chemistry offers better process control or economic advantage over alternative tungsten compounds.

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.
