Chemical Structure

Magnesium fluorosilicate hexahydrate CAS 16949-65-8 chemical structure

Description

The occurrence of Magnesium fluorosilicate hexahydrate is closely related to fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Magnesium fluorosilicate hexahydrate (CAS 16949-65-8), molecular formula F6SiMg and molecular weight 166.38 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to fluorine substitution, Magnesium fluorosilicate hexahydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 fluorosilicate hexahydrate 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.
