(R)-3,3'-Dibromo-2,2'-dimethoxy-1,1'-binaphthyl CAS 75714-59-9

Description

(R)-3,3'-Dibromo-2,2'-dimethoxy-1,1'-binaphthyl (CAS 75714-59-9), molecular formula C22H16Br2O2 and molecular weight 472.17 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (R)-3,3'-Dibromo-2,2'-dimethoxy-1,1'-binaphthyl (C22H16Br2O2) is characterized by a steroid core, a hydroxyl group, an ether linkage, bromine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures (R)-3,3'-Dibromo-2,2'-dimethoxy-1,1'-binaphthyl 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.
