4-(4,4-Dimethyl-cyclohexyl)-3-oxo-butyric acid ethyl ester CAS 1414958-05-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(4,4-Dimethyl-cyclohexyl)-3-oxo-butyric acid ethyl ester.

4-(4,4-Dimethyl-cyclohexyl)-3-oxo-butyric acid ethyl ester (CAS 1414958-05-6), molecular formula C14H24O3 and molecular weight 240.34 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-(4,4-Dimethyl-cyclohexyl)-3-oxo-butyric acid ethyl ester (C14H24O3) is characterized by 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).

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.
