Chemical Structure
Description
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.
2-((2-Chloroethyl)sulfonyl)ethan-1-ol (CAS 25906-30-3) is a high-purity analytical reference standard with the molecular formula C4H9ClO3S and a molecular weight of 172.63 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 2-((2-Chloroethyl)sulfonyl)ethan-1-ol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
