Compared with other compounds in its class, the molecular weight of 203.64 g/mol gives 2-(1-Iminoethoxy)ethanesulfonic acid hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(1-Iminoethoxy)ethanesulfonic acid hydrochloride (CAS 94732-92-0), molecular formula C4H9NO4SHCl and molecular weight 203.64 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(1-Iminoethoxy)ethanesulfonic acid hydrochloride (C4H9NO4SHCl) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
