Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 239.11 g/mol gives 5-Bromo-2,2-dimethyl-2,3-dihydro-1H-inden-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Bromo-2,2-dimethyl-2,3-dihydro-1H-inden-1-one (CAS 495414-32-9) is a high-purity analytical reference standard with the molecular formula C11H11BrO and a molecular weight of 239.11 g/mol.
The molecular framework of 5-Bromo-2,2-dimethyl-2,3-dihydro-1H-inden-1-one (C11H11BrO) is characterized by a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 5-Bromo-2,2-dimethyl-2,3-dihydro-1H-inden-1-one 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.
