As a certified reference material (CRM), Chloromethyl Chlorosulfonate 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.
Chloromethyl Chlorosulfonate (CAS 49715-04-0), molecular formula CH2Cl2O3S and molecular weight 165.00 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, chlorine substitution, Chloromethyl Chlorosulfonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 165.00 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.
