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-(3,4-Bis(benzyloxy)phenyl)acrylic acid.
CATO supplies (E)-3-(3,4-Bis(benzyloxy)phenyl)acrylic acid (CAS 179128-93-9), a certified reference material (molecular formula C23H20O4, MW 360.40 g/mol) for analytical method development and quality control.
Structurally, (E)-3-(3,4-Bis(benzyloxy)phenyl)acrylic acid (C23H20O4) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 360.40 g/mol, it falls into the moderately-high-molecular-weight range. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
