Chemical Structure

(1R,2S,5R)-2-isopropyl-5-methylcyclohexyl (S)-(hydroxymethyl)phosphinate CAS 1611990-03-4 chemical structure

Description

As a certified reference material (CRM), (1R,2S,5R)-2-isopropyl-5-methylcyclohexyl (S)-(hydroxymethyl)phosphinate 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.

(1R,2S,5R)-2-isopropyl-5-methylcyclohexyl (S)-(hydroxymethyl)phosphinate (CAS 1611990-03-4), molecular formula C11H23O3P and molecular weight 234.27 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H23O3P, (1R,2S,5R)-2-isopropyl-5-methylcyclohexyl (S)-(hydroxymethyl)phosphinate contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 234.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
