Chemical Structure

bis(2-ethylhexyl) cyclohexane-1,4-dicarboxylate CAS 84731-70-4 chemical structure

Description

bis(2-ethylhexyl) cyclohexane-1,4-dicarboxylate (CAS 84731-70-4), molecular formula C24H44O4 and molecular weight 396.60 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, bis(2-ethylhexyl) cyclohexane-1,4-dicarboxylate (C24H44O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 396.60 g/mol, it falls into the moderately-high-molecular-weight range. 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.
