5-bromo-6-chloro-2,3-dihydro-1H-indene (CAS 1781866-76-9) is a high-purity analytical reference standard with the molecular formula C9H8BrCl and a molecular weight of 231.52 g/mol.
Owing to chlorine/bromine substitution, an aromatic ring system, 5-bromo-6-chloro-2,3-dihydro-1H-indene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.52 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).
CATO manufactures 5-bromo-6-chloro-2,3-dihydro-1H-indene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
