Chemical Structure
Description
2,3-Dichloro-7-hydroxy-4-methyl-1H-inden-1-one (CAS 75376-47-5) is a high-purity analytical reference standard with the molecular formula C10H6Cl2O2 and a molecular weight of 229.06 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2,3-Dichloro-7-hydroxy-4-methyl-1H-inden-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 2,3-Dichloro-7-hydroxy-4-methyl-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.
