Description
Compared with other compounds in its class, the molecular weight of 367.36 g/mol gives 4-Iodophenyl isothiocyanate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Iodophenyl isothiocyanate (CAS 2059-76-9), a certified reference material (molecular formula C19H17N3O5, MW 367.36 g/mol) for analytical method development and quality control.
4-Iodophenyl isothiocyanate (C19H17N3O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Iodophenyl isothiocyanate 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.
