Chemical Structure
Description
2-(2-HYdroxyethoxy)ethyl methanesulfonate (CAS 118591-57-4), molecular formula C5H12O5S and molecular weight 184.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(2-HYdroxyethoxy)ethyl methanesulfonate (C5H12O5S) is characterized by a carbohydrate-derived structure, a sulfone group. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
