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.
CATO supplies 2-(3-Methyl-3H-diazirin-3-yl)ethane-1-sulfonyl chloride (CAS 1909335-97-2), a certified reference material (molecular formula C4H7ClN2O2S, MW 182.63 g/mol) for analytical method development and quality control.
2-(3-Methyl-3H-diazirin-3-yl)ethane-1-sulfonyl chloride (C4H7ClN2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 2-(3-Methyl-3H-diazirin-3-yl)ethane-1-sulfonyl 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.
