Chemical Structure
Description
CATO supplies (11bR)-2,6-bis(3,5-difluorophenyl)-3,3,5,5-tetraoxide-dinaphtho[2,1-d:1',2'-f][1,3,2]dithiazepine (CAS 1245748-62-2), a certified reference material (molecular formula C32H17F4NO4S2, MW 619.61 g/mol) for analytical method development and quality control.
The molecular framework of (11bR)-2,6-bis(3,5-difluorophenyl)-3,3,5,5-tetraoxide-dinaphtho[2,1-d:1',2'-f][1,3,2]dithiazepine (C32H17F4NO4S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
