Chemical Structure

cis-Aconitic acid CAS 585-84-2 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.

CATO supplies cis-Aconitic acid (CAS 585-84-2), a certified reference material (molecular formula C6H6O6, MW 174.11 g/mol) for analytical method development and quality control.

cis-Aconitic acid (C6H6O6) contains a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), cis-Aconitic acid 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.
