Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 9-(4-Fluorophenyl)-7-(thiophen-2-yl)thieno[2,3-b:4,5-b']dipyridine-2,4-diol (CAS 290300-02-6), a certified reference material (molecular formula C20H11FN2O2S2, MW 394.44 g/mol) for analytical method development and quality control.
The molecular framework of 9-(4-Fluorophenyl)-7-(thiophen-2-yl)thieno[2,3-b:4,5-b']dipyridine-2,4-diol (C20H11FN2O2S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 9-(4-Fluorophenyl)-7-(thiophen-2-yl)thieno[2,3-b:4,5-b']dipyridine-2,4-diol 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.
