Chemical Structure
Description
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 supplies 11B-benzyl-9-hydroxy-5,6,7,11b-tetrahydro-1H-dibenzo[a,c][7]annulen-3(2H)-one (CAS 1400924-57-3), a certified reference material (molecular formula C22H22O2, MW 318.41 g/mol) for analytical method development and quality control.
The molecular framework of 11B-benzyl-9-hydroxy-5,6,7,11b-tetrahydro-1H-dibenzo[a,c][7]annulen-3(2H)-one (C22H22O2) 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 11B-benzyl-9-hydroxy-5,6,7,11b-tetrahydro-1H-dibenzo[a,c][7]annulen-3(2H)-one 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.
