The occurrence of Sulfamoyl Chloride is closely related to a sulfone group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Sulfamoyl Chloride (CAS 7778-42-9) is a high-purity analytical reference standard with the molecular formula H2ClNO2S and a molecular weight of 115.54 g/mol.
Based on its molecular formula H2ClNO2S, Sulfamoyl Chloride contains a sulfone group, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 115.54 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.
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), Sulfamoyl Chloride 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.
