Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies N-(4-Hydroxy-3-methoxyphenethyl)-2-(3-hydroxy-4-methoxyphenyl)acetamide (CAS 21411-19-8), a certified reference material (molecular formula C18H21NO5, MW 331.36 g/mol) for analytical method development and quality control.
N-(4-Hydroxy-3-methoxyphenethyl)-2-(3-hydroxy-4-methoxyphenyl)acetamide (C18H21NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
CATO manufactures N-(4-Hydroxy-3-methoxyphenethyl)-2-(3-hydroxy-4-methoxyphenyl)acetamide 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.
