Chemical Structure
Description
The occurrence of (3,4-Dimethoxy-5-(methylselanyl)phenyl)(3-hydroxy-4-methoxyphenyl)methanone 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 (3,4-Dimethoxy-5-(methylselanyl)phenyl)(3-hydroxy-4-methoxyphenyl)methanone (CAS 2123478-00-0), a certified reference material (molecular formula C17H18O5Se, MW 381.28 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, (3,4-Dimethoxy-5-(methylselanyl)phenyl)(3-hydroxy-4-methoxyphenyl)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 381.28 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 (3,4-Dimethoxy-5-(methylselanyl)phenyl)(3-hydroxy-4-methoxyphenyl)methanone 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.
