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 Butanedioic acid, 2-methylene-, polymer with 2-propenoic acid, sodium salt (CAS 26099-88-7), a certified reference material (molecular formula C5H6O4C3H3O2Na, MW 224.14 g/mol) for analytical method development and quality control.
The molecular framework of Butanedioic acid, 2-methylene-, polymer with 2-propenoic acid, sodium salt (C5H6O4C3H3O2Na) 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).
As a certified reference material (CRM), Butanedioic acid, 2-methylene-, polymer with 2-propenoic acid, sodium 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.
