CATO supplies tert-butyl 3-[(chlorosulfonyl)methyl]oxetane-3-carboxylate (CAS 1955519-85-3), a certified reference material (molecular formula C9H15ClO5S, MW 270.73 g/mol) for analytical method development and quality control.
tert-butyl 3-[(chlorosulfonyl)methyl]oxetane-3-carboxylate (C9H15ClO5S) contains 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.
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.
