Chemical Structure
Description
CATO supplies Silver(I) 2-carboxyphenolate (CAS 528-93-8), a certified reference material (molecular formula C7H5O3Ag, MW 244.98 g/mol) for analytical method development and quality control.
The molecular framework of Silver(I) 2-carboxyphenolate (C7H5O3Ag) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).
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), Silver(I) 2-carboxyphenolate 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.
