Chemical Structure

2-Ethyl-4-methylphenol CAS 3855-26-3 chemical structure

Description

Based on its molecular formula C9H18O, 2-Ethyl-4-methylphenol contains a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 142.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

2-Ethyl-4-methylphenol (CAS 3855-26-3) is a high-purity analytical reference standard with the molecular formula C9H18O and a molecular weight of 142.24 g/mol.

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.
