Chemical Structure

ethyl 2-cyano-2-ethyl-3-methylpentanoate CAS 71172-92-4 chemical structure

Description

The occurrence of ethyl 2-cyano-2-ethyl-3-methylpentanoate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies ethyl 2-cyano-2-ethyl-3-methylpentanoate (CAS 71172-92-4), a certified reference material (molecular formula C11H19NO2, MW 197.27 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, ethyl 2-cyano-2-ethyl-3-methylpentanoate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 197.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), ethyl 2-cyano-2-ethyl-3-methylpentanoate 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.
