Description

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.

CATO supplies 2-((2Z,5E)-5-(((3AR,8BR)-4-(4-(2,2-DIPHENYLVINYL)PHENYL)-1,2,3,3A,4,8B-HEXAHYDROCYCLOPENTA[B]INDOL-7-YL)METHYLENE)-3'-ETHYL-4,4'-DIOXO-2'-THIOXO-3',4,4',5-TETRAHYDRO-2'H,3H-[2,5'-BITHIAZOLYLIDENE]-3-YL)ACETIC ACID 786643-20-7 W-6117 (CAS 786643-20-7), a certified reference material (molecular formula C42H59N3O4S3, MW 766.13 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-((2Z,5E)-5-(((3AR,8BR)-4-(4-(2,2-DIPHENYLVINYL)PHENYL)-1,2,3,3A,4,8B-HEXAHYDROCYCLOPENTA[B]INDOL-7-YL)METHYLENE)-3'-ETHYL-4,4'-DIOXO-2'-THIOXO-3',4,4',5-TETRAHYDRO-2'H,3H-[2,5'-BITHIAZOLYLIDENE]-3-YL)ACETIC ACID 786643-20-7 W-6117 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 766.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
