Chemical Structure
Description
Based on its molecular formula C4H8ClO4SNa, Sodium 4-chloro-1-hydroxybutanesulfonate contains a salt form, a carbohydrate-derived structure, a sulfone group, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 210.60 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies Sodium 4-chloro-1-hydroxybutanesulfonate (CAS 54322-20-2), a certified reference material (molecular formula C4H8ClO4SNa, MW 210.60 g/mol) for analytical method development and quality control.
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.
