The occurrence of (11bR)-2,6-diiodo-3,3,5,5-tetraoxide-dinaphtho[2,1-d:1',2'-f][1,3,2]dithiazepine is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (11bR)-2,6-diiodo-3,3,5,5-tetraoxide-dinaphtho[2,1-d:1',2'-f][1,3,2]dithiazepine (CAS 1245748-53-1), a certified reference material (molecular formula C20H11I2NO4S2, MW 647.24 g/mol) for analytical method development and quality control.
(11bR)-2,6-diiodo-3,3,5,5-tetraoxide-dinaphtho[2,1-d:1',2'-f][1,3,2]dithiazepine (C20H11I2NO4S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
