Chemical Structure
Description
(1S,2R,5S)-2-isopropyl-5-methylcyclohexyl (2S,5S)-5-hydroxy-1,3-oxathiolane-2-carboxylate (CAS 1638744-50-9) is a high-purity analytical reference standard with the molecular formula C14H24O4S and a molecular weight of 288.40 g/mol.
The molecular framework of (1S,2R,5S)-2-isopropyl-5-methylcyclohexyl (2S,5S)-5-hydroxy-1,3-oxathiolane-2-carboxylate (C14H24O4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
As a certified reference material (CRM), (1S,2R,5S)-2-isopropyl-5-methylcyclohexyl (2S,5S)-5-hydroxy-1,3-oxathiolane-2-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
