Chemical Structure

Magnesiumsalicylate CAS 18917-89-0 chemical structure

Description

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.

Magnesiumsalicylate (CAS 18917-89-0) is a high-purity analytical reference standard with the molecular formula C7H5O3Mg and a molecular weight of 161.42 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Magnesiumsalicylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 161.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), Magnesiumsalicylate 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.
