Chemical Structure

Magnesium trisilicate hydrate CAS 39365-87-2 chemical structure

Description

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

Magnesium trisilicate hydrate (CAS 39365-87-2), molecular formula O8Si3MgH2O and molecular weight 254.57 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Magnesium trisilicate hydrate (O8Si3MgH2O) 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.

As a certified reference material (CRM), Magnesium trisilicate 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.
