Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 153.15 g/mol gives Fumaric acid xpotassium salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Fumaric acid xpotassium salt (CAS 7704-72-5), a certified reference material (molecular formula C4H2O4K, MW 153.15 g/mol) for analytical method development and quality control.
The molecular framework of Fumaric acid xpotassium salt (C4H2O4K) is characterized by a carbohydrate-derived structure. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Fumaric acid xpotassium salt 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.
