Description
As a certified reference material (CRM), tert-Butyl (4-(4-bromophenylsulfonamido)-4-oxobutyl)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.
tert-Butyl (4-(4-bromophenylsulfonamido)-4-oxobutyl)carbamate (CAS 2044702-83-0) is a high-purity analytical reference standard with the molecular formula C15H21BrN2O5S and a molecular weight of 421.31 g/mol.
tert-Butyl (4-(4-bromophenylsulfonamido)-4-oxobutyl)carbamate (C15H21BrN2O5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine 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. 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.
