Chemical Structure

(1S,2R,5S)-2-isopropyl-5-methylcyclohexyl acetate CAS 5157-89-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1S,2R,5S)-2-isopropyl-5-methylcyclohexyl acetate.

CATO supplies (1S,2R,5S)-2-isopropyl-5-methylcyclohexyl acetate (CAS 5157-89-1), a certified reference material (molecular formula C12H22O2, MW 198.30 g/mol) for analytical method development and quality control.

(1S,2R,5S)-2-isopropyl-5-methylcyclohexyl acetate (C12H22O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
