Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4'-Methoxy-3'-methyl-[1,2'-binaphthalene]-1',2-diol (CAS 1832513-80-0), molecular formula C22H18O3 and molecular weight 330.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4'-Methoxy-3'-methyl-[1,2'-binaphthalene]-1',2-diol (C22H18O3) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 4'-Methoxy-3'-methyl-[1,2'-binaphthalene]-1',2-diol 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.
