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 3,3-Bis(3,4-dimethoxyphenyl)propanoic acid (CAS 6256-05-9), a certified reference material (molecular formula C19H22O6, MW 346.37 g/mol) for analytical method development and quality control.
3,3-Bis(3,4-dimethoxyphenyl)propanoic acid (C19H22O6) contains a flavonoid core, 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 3,3-Bis(3,4-dimethoxyphenyl)propanoic acid 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.
