Chemical Structure
Description
The occurrence of 6-Chloro-2,3-diphenyl-1H-indole is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 6-Chloro-2,3-diphenyl-1H-indole (CAS 66785-53-3), a certified reference material (molecular formula C10H18O6S2, MW 298.38 g/mol) for analytical method development and quality control.
The molecular framework of 6-Chloro-2,3-diphenyl-1H-indole (C10H18O6S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
