Chemical Structure

Sodium metaborate hydrate CAS 15293-77-3 chemical structure

Description

The occurrence of Sodium metaborate hydrate is closely related to an inorganic composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Sodium metaborate hydrate (CAS 15293-77-3), a certified reference material (molecular formula BO2NaH2O, MW 83.81 g/mol) for analytical method development and quality control.

Structurally, Sodium metaborate hydrate (BO2NaH2O) contains an inorganic composition. 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 83.81 g/mol, it falls into the low-molecular-weight range.

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.

As a certified reference material (CRM), Sodium metaborate hydrate 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.
