Chemical Structure
Description
As a certified reference material (CRM), 11B-benzyl-9-hydroxy-4,4a,5,6,7,11b-hexahydro-1H-dibenzo[a,c][7]annulen-3(2H)-one 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.
11B-benzyl-9-hydroxy-4,4a,5,6,7,11b-hexahydro-1H-dibenzo[a,c][7]annulen-3(2H)-one (CAS 1400927-78-7), molecular formula C22H24O2 and molecular weight 320.42 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 11B-benzyl-9-hydroxy-4,4a,5,6,7,11b-hexahydro-1H-dibenzo[a,c][7]annulen-3(2H)-one (C22H24O2) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
