CATO supplies 2-(3-Iodophenyl)isothiazolidine 1,1-dioxide (CAS 1228776-05-3), a certified reference material (molecular formula C9H10INO2S, MW 323.15 g/mol) for analytical method development and quality control.
2-(3-Iodophenyl)isothiazolidine 1,1-dioxide (C9H10INO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 manufactures 2-(3-Iodophenyl)isothiazolidine 1,1-dioxide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
