Chemical Structure
Description
The occurrence of (E)-2,3-Bis(3,4-dimethoxyphenyl)acrylic Acid is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (E)-2,3-Bis(3,4-dimethoxyphenyl)acrylic Acid (CAS 24316-12-9), a certified reference material (molecular formula C19H20O6, MW 344.36 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, (E)-2,3-Bis(3,4-dimethoxyphenyl)acrylic Acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 344.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (E)-2,3-Bis(3,4-dimethoxyphenyl)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.
