Chemical Structure
Description
Bismuth tungsten oxide (CAS 13595-87-4) is a high-purity analytical reference standard with the molecular formula BiWO and a molecular weight of 408.82 g/mol.
The molecular framework of Bismuth tungsten oxide (BiWO) is characterized by an inorganic composition. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
CATO manufactures Bismuth tungsten oxide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
