(5S)-2,3-Dimethyl-5-(prop-1-en-2-yl)cyclohex-2-en-1-one (CAS 85710-66-3), molecular formula C11H16O and molecular weight 164.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (5S)-2,3-Dimethyl-5-(prop-1-en-2-yl)cyclohex-2-en-1-one (C11H16O) is characterized by a hydroxyl group, an ether linkage, 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).
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.
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.
