Chemical Structure
Description
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 1-Benzyl-4-(5,6-dimethoxy-1-oxo-2,3-dihydro-1H-indene-2-carbonyl)pyridin-1-ium bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 468.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
1-Benzyl-4-(5,6-dimethoxy-1-oxo-2,3-dihydro-1H-indene-2-carbonyl)pyridin-1-ium bromide (CAS 923571-17-9), molecular formula C24H22NO4Br and molecular weight 468.35 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-Benzyl-4-(5,6-dimethoxy-1-oxo-2,3-dihydro-1H-indene-2-carbonyl)pyridin-1-ium bromide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
