Chemical Structure

sodium 1-chloroethane-1-sulfonate CAS 116277-82-8 chemical structure

Description

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.

sodium 1-chloroethane-1-sulfonate (CAS 116277-82-8), molecular formula C2H4ClO3SNa and molecular weight 166.55 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of sodium 1-chloroethane-1-sulfonate (C2H4ClO3SNa) is characterized by a salt form, a sulfone group, a carboxylic acid group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
