Chemical Structure

Diethyl 2-ethyl-2-(4-methylpentan-2-yl)malonate CAS 36075-05-5 chemical structure

Description

Diethyl 2-ethyl-2-(4-methylpentan-2-yl)malonate (CAS 36075-05-5) is a high-purity analytical reference standard with the molecular formula C15H28O4 and a molecular weight of 272.38 g/mol.

Structurally, Diethyl 2-ethyl-2-(4-methylpentan-2-yl)malonate (C15H28O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 272.38 g/mol, it falls into the medium-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.
