Chemical Structure

3-Ethylpentanenitrile CAS 5631-83-4 chemical structure

Description

Owing to a nitrile group, 3-Ethylpentanenitrile is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 111.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

3-Ethylpentanenitrile (CAS 5631-83-4), molecular formula C7H13N and molecular weight 111.18 g/mol, is a CATO reference standard with documented purity and traceability.

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), 3-Ethylpentanenitrile 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.
