Compared with other compounds in its class, the molecular weight of 153.53 g/mol gives Sodium chloromethylsulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Sodium chloromethylsulfonate (CAS 10352-63-3), a certified reference material (molecular formula CH3ClO3SNa, MW 153.53 g/mol) for analytical method development and quality control.
Owing to a salt form, a sulfone group, chlorine substitution, Sodium chloromethylsulfonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 153.53 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.
As a certified reference material (CRM), Sodium chloromethylsulfonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
