Compared with other compounds in its class, the molecular weight of 135.14 g/mol gives ethanesulfonyl isocyanate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
ethanesulfonyl isocyanate (CAS 14604-85-4), molecular formula C3H5NO3S and molecular weight 135.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of ethanesulfonyl isocyanate (C3H5NO3S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures ethanesulfonyl isocyanate 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.
