Description

The occurrence of 3,3-HEPTANEDIOIC ACID,6-METHYL,DIETHYLESTER (ISOAMYLETHYLMALONATE DIETHYLESTER) 77-24-7 InChI=1/C14H26O4/c1-6-14(10-9-11(4)5,12(15)17-7-2)13(16)18-8-3/h11H,6-10H2,1-5H diethyl ethyl(3-methylbutyl)malonate propanedioic acid, ethyl(3-methylbutyl)-, diethyl ester is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,3-HEPTANEDIOIC ACID,6-METHYL,DIETHYLESTER (ISOAMYLETHYLMALONATE DIETHYLESTER) 77-24-7 InChI=1/C14H26O4/c1-6-14(10-9-11(4)5,12(15)17-7-2)13(16)18-8-3/h11H,6-10H2,1-5H diethyl ethyl(3-methylbutyl)malonate propanedioic acid, ethyl(3-methylbutyl)-, diethyl ester (CAS 77-24-7) is a high-purity analytical reference standard with the molecular formula C8H5O4K and a molecular weight of 204.22 g/mol.

The molecular framework of 3,3-HEPTANEDIOIC ACID,6-METHYL,DIETHYLESTER (ISOAMYLETHYLMALONATE DIETHYLESTER) 77-24-7 InChI=1/C14H26O4/c1-6-14(10-9-11(4)5,12(15)17-7-2)13(16)18-8-3/h11H,6-10H2,1-5H diethyl ethyl(3-methylbutyl)malonate propanedioic acid, ethyl(3-methylbutyl)-, diethyl ester (C8H5O4K) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
