Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 5-bromo-2,3-dihydro-1-oxo-1H-indene-2-carboxylate.
Methyl 5-bromo-2,3-dihydro-1-oxo-1H-indene-2-carboxylate (CAS 628732-08-1) is a high-purity analytical reference standard with the molecular formula C11H9BrO3 and a molecular weight of 269.09 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, Methyl 5-bromo-2,3-dihydro-1-oxo-1H-indene-2-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 269.09 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Methyl 5-bromo-2,3-dihydro-1-oxo-1H-indene-2-carboxylate 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.
