Chemical Structure
Description
CATO supplies 1-Bromo-5-chloro-2,3-dihydro-1H-indene (CAS 192702-71-9), a certified reference material (molecular formula C9H8BrCl, MW 231.52 g/mol) for analytical method development and quality control.
The molecular framework of 1-Bromo-5-chloro-2,3-dihydro-1H-indene (C9H8BrCl) is characterized by chlorine/bromine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
