Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
Tungsten carbide (CAS 12070-12-1), molecular formula CW and molecular weight 195.85 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an organic framework, Tungsten carbide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 195.85 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
As a certified reference material (CRM), Tungsten carbide 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.
