Chemical Structure

(2E)-4-Methyl-2-pentenenitrile CAS 19124-15-3 chemical structure

Description

CATO supplies (2E)-4-Methyl-2-pentenenitrile (CAS 19124-15-3), a certified reference material (molecular formula C6H9N, MW 95.14 g/mol) for analytical method development and quality control.

Owing to a nitrile group, (2E)-4-Methyl-2-pentenenitrile is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 95.14 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.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
