Chemical Structure

(E)-4-Methylpent-2-enoic acid CAS 16666-43-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 114.14 g/mol gives (E)-4-Methylpent-2-enoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (E)-4-Methylpent-2-enoic acid (CAS 16666-43-6), a certified reference material (molecular formula C6H10O2, MW 114.14 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (E)-4-Methylpent-2-enoic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 114.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
