Chemical Structure

2-(2,2-Dimethoxyacetyl)-4-methylcyclohexan-1-one CAS 1342988-63-9 chemical structure

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.

2-(2,2-Dimethoxyacetyl)-4-methylcyclohexan-1-one (CAS 1342988-63-9), molecular formula C11H18O4 and molecular weight 214.26 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H18O4, 2-(2,2-Dimethoxyacetyl)-4-methylcyclohexan-1-one contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 214.26 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.

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.
