Chemical Structure

Dimethyl (1-ethylpropyl)malonate CAS 39520-19-9 chemical structure

Description

Dimethyl (1-ethylpropyl)malonate (CAS 39520-19-9) is a high-purity analytical reference standard with the molecular formula C10H18O4 and a molecular weight of 202.25 g/mol.

The molecular framework of Dimethyl (1-ethylpropyl)malonate (C10H18O4) 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 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.

CATO manufactures Dimethyl (1-ethylpropyl)malonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
