Chemical Structure
Description
The occurrence of 7-Methoxy-3-(4'-methoxyphenyl)coumarin 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.
7-Methoxy-3-(4'-methoxyphenyl)coumarin (CAS 3173-00-0) is a high-purity analytical reference standard with the molecular formula C17H14O4 and a molecular weight of 282.29 g/mol.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 7-Methoxy-3-(4'-methoxyphenyl)coumarin is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 282.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures 7-Methoxy-3-(4'-methoxyphenyl)coumarin under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
