Chemical Structure
Description
As a certified reference material (CRM), Ethanesulfinyl 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.
CATO supplies Ethanesulfinyl chloride (CAS 1718-44-1), a certified reference material (molecular formula C2H5ClOS, MW 112.58 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, Ethanesulfinyl chloride is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 112.58 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.
