Chemical Structure
Description
2-ethylhexyl methanesulfonate (CAS 92885-97-7) is a high-purity analytical reference standard with the molecular formula C9H20O3S and a molecular weight of 208.32 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 2-ethylhexyl methanesulfonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 208.32 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.
