Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
tert-butyl N-{3-[2-(methanesulfonyloxy)propyl]pyridin-4-yl}carbamate (CAS 257937-11-4), molecular formula C14H22N2O5S and molecular weight 330.40 g/mol, is a CATO reference standard with documented purity and traceability.
tert-butyl N-{3-[2-(methanesulfonyloxy)propyl]pyridin-4-yl}carbamate (C14H22N2O5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.
As a certified reference material (CRM), tert-butyl N-{3-[2-(methanesulfonyloxy)propyl]pyridin-4-yl}carbamate 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.
