Chemical Structure

(E)-4-ethyl-2-methyl-oct-2-enoic acid CAS 6975-97-9 chemical structure

Description

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.

CATO supplies (E)-4-ethyl-2-methyl-oct-2-enoic acid (CAS 6975-97-9), a certified reference material (molecular formula C11H20O2, MW 184.28 g/mol) for analytical method development and quality control.

The molecular framework of (E)-4-ethyl-2-methyl-oct-2-enoic acid (C11H20O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
