Description
Vanadium(III) Chloride (CAS 7718-98-1, EC 231-744-6) is an inorganic vanadium salt supplied as a powder and commonly referenced as VCl3 or Vanadium Trichloride. It carries no E-code designation and is classified under HS code 28273990 within the Salts & Minerals category.
VCl3 functions primarily as a catalyst and polymerization initiator in the plastics and polymers industry. In Ziegler-Natta-type systems, it activates monomer coordination at the metal centre, enabling controlled synthesis of polyolefins such as polyethylene and polypropylene. It is also employed as a precursor in the preparation of other vanadium-based catalytic compounds.
This product is available in powder form and is subject to REACH registration requirements applicable within the European Economic Area. Procurement teams should confirm supplier documentation including Safety Data Sheets and certificates of analysis. Packaging formats vary by supplier; buyers should specify quantity and containment requirements at the time of enquiry.
