Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-3-(2-(2-((4-ethoxyphenyl)amino)-2-oxoethoxy)phenyl)acrylic acid.
CATO supplies (E)-3-(2-(2-((4-ethoxyphenyl)amino)-2-oxoethoxy)phenyl)acrylic acid (CAS 937599-34-3), a certified reference material (molecular formula C19H19NO5, MW 341.36 g/mol) for analytical method development and quality control.
Structurally, (E)-3-(2-(2-((4-ethoxyphenyl)amino)-2-oxoethoxy)phenyl)acrylic acid (C19H19NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 341.36 g/mol, it falls into the moderately-high-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), (E)-3-(2-(2-((4-ethoxyphenyl)amino)-2-oxoethoxy)phenyl)acrylic 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.
