Chemical Structure

Magnesium Metaphosphate CAS 13573-12-1 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Magnesium Metaphosphate (CAS 13573-12-1), molecular formula O3PMg and molecular weight 103.28 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula O3PMg, Magnesium Metaphosphate contains a phosphonate group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 103.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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