(1R,2S,5R)-2-isopropyl-5-methylcyclohexyl (2S,5S)-5-acetoxy-1,3-oxathiolane-2-carboxylate CAS 147126-66-7

Description

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 supplies (1R,2S,5R)-2-isopropyl-5-methylcyclohexyl (2S,5S)-5-acetoxy-1,3-oxathiolane-2-carboxylate (CAS 147126-66-7), a certified reference material (molecular formula C16H26O5S, MW 330.44 g/mol) for analytical method development and quality control.

The molecular framework of (1R,2S,5R)-2-isopropyl-5-methylcyclohexyl (2S,5S)-5-acetoxy-1,3-oxathiolane-2-carboxylate (C16H26O5S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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 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).

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.
