2,4-Dimethylhexane CAS 589-43-5 chemical structure

Description

2,4-Dimethylhexane (CAS 589-43-5) is a high-purity analytical reference standard with the molecular formula C8H18 and a molecular weight of 114.23 g/mol.

Based on its molecular formula C8H18, 2,4-Dimethylhexane contains an organic framework; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 114.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
