Chemical Structure
Description
7-Chloro-3,3-dimethyl-2,3-dihydro-1H-inden-5-ol (CAS 65021-26-3), molecular formula C11H13ClO and molecular weight 196.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Chloro-3,3-dimethyl-2,3-dihydro-1H-inden-5-ol (C11H13ClO) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
