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 DIMETHYL 2,2’-DIMETHOXY-[1,1’-BIPHENYL]-3,3’-DICARBOXYLATE (CAS 156660-23-0), a certified reference material (molecular formula C18H18O6, MW 330.33 g/mol) for analytical method development and quality control.
DIMETHYL 2,2’-DIMETHOXY-[1,1’-BIPHENYL]-3,3’-DICARBOXYLATE (C18H18O6) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), DIMETHYL 2,2’-DIMETHOXY-[1,1’-BIPHENYL]-3,3’-DICARBOXYLATE meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
