Chemical Structure
Description
5-Fluoro-7-hydroxy-2,3-dihydro-1H-inden-1-one (CAS 1260013-93-1) is a high-purity analytical reference standard with the molecular formula C9H7FO2 and a molecular weight of 166.15 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 5-Fluoro-7-hydroxy-2,3-dihydro-1H-inden-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 5-Fluoro-7-hydroxy-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.
