Chemical Structure
Description
CATO supplies 2,3-Bis(4-(diphenylamino)phenyl)benzo[b]thiophene 1,1-dioxide (CAS 2091868-86-7), a certified reference material (molecular formula C44H32N2O2S, MW 652.80 g/mol) for analytical method development and quality control.
The molecular framework of 2,3-Bis(4-(diphenylamino)phenyl)benzo[b]thiophene 1,1-dioxide (C44H32N2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,3-Bis(4-(diphenylamino)phenyl)benzo[b]thiophene 1,1-dioxide 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.
