Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3,3',5,5'-Tetramethoxy-bibenzyl (CAS 22976-41-6), molecular formula C18H22O4 and molecular weight 302.36 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3,3',5,5'-Tetramethoxy-bibenzyl (C18H22O4) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 302.36 g/mol, it falls into the moderately-high-molecular-weight range. 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',5,5'-Tetramethoxy-bibenzyl 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.
