Diethyl 2-methylpentanedioate CAS 18545-83-0

Description

Compared with other compounds in its class, the molecular weight of 202.25 g/mol gives Diethyl 2-methylpentanedioate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Diethyl 2-methylpentanedioate (CAS 18545-83-0), a certified reference material (molecular formula C10H18O4, MW 202.25 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Diethyl 2-methylpentanedioate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Diethyl 2-methylpentanedioate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
