Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 166.60 g/mol gives 2-Chloro-2,3-dihydro-1h-inden-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Chloro-2,3-dihydro-1h-inden-1-one (CAS 1579-14-2), molecular formula C9H7ClO and molecular weight 166.60 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Chloro-2,3-dihydro-1h-inden-1-one (C9H7ClO) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 2-Chloro-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.
