Chemical Structure
Description
The occurrence of Sodium (E)-3-carboxyacrylate is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Sodium (E)-3-carboxyacrylate (CAS 5873-57-4), a certified reference material (molecular formula C4H3O4Na, MW 138.05 g/mol) for analytical method development and quality control.
Structurally, Sodium (E)-3-carboxyacrylate (C4H3O4Na) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 138.05 g/mol, it falls into the low-molecular-weight range. 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), Sodium (E)-3-carboxyacrylate 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.
