Chemical Structure
Description
As a certified reference material (CRM), 4-[(2E)-3-(2H-1,3-Benzodioxol-5-yl)prop-2-enoyl]phenyl thiophene-2-carboxylate 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.
CATO supplies 4-[(2E)-3-(2H-1,3-Benzodioxol-5-yl)prop-2-enoyl]phenyl thiophene-2-carboxylate (CAS 306730-09-6), a certified reference material (molecular formula C21H14O5S, MW 378.40 g/mol) for analytical method development and quality control.
The molecular framework of 4-[(2E)-3-(2H-1,3-Benzodioxol-5-yl)prop-2-enoyl]phenyl thiophene-2-carboxylate (C21H14O5S) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
