Chemical Structure

Tungsten(IV) chloride CAS 13470-13-8 chemical structure

Description

Tungsten(IV) chloride (CAS 13470-13-8), molecular formula Cl4W and molecular weight 325.65 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Tungsten(IV) chloride (Cl4W) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 325.65 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Tungsten(IV) chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
