Chemical Structure

[Ethanedioato(2-)-κO1,κO2]manganese CAS 640-67-5 chemical structure

Description

CATO supplies [Ethanedioato(2-)-κO1,κO2]manganese (CAS 640-67-5), a certified reference material (molecular formula C2MnO4, MW 142.96 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, an ether linkage, [Ethanedioato(2-)-κO1,κO2]manganese is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.96 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).

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), [Ethanedioato(2-)-κO1,κO2]manganese 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.
