Chemical Structure

Tungsten trioxide hydrate (3:1) CAS 78798-95-5 chemical structure

Description

The occurrence of Tungsten trioxide hydrate (3:1) is closely related to an inorganic composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Tungsten trioxide hydrate (3:1) (CAS 78798-95-5), a certified reference material (molecular formula O3WH2O, MW 249.85 g/mol) for analytical method development and quality control.

The molecular framework of Tungsten trioxide hydrate (3:1) (O3WH2O) 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 Tungsten trioxide hydrate (3:1) 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.
