Description
CATO manufactures 5-Chloro-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.
5-Chloro-2,2-dimethyl-2,3-dihydro-1H-inden-1-one (CAS 118259-88-4) is a high-purity analytical reference standard with the molecular formula C11H11ClO and a molecular weight of 194.66 g/mol.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 5-Chloro-2,2-dimethyl-2,3-dihydro-1H-inden-1-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 194.66 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).
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.
