Chemical Structure
Description
The molecular framework of 2-(Dansylsulfonamido)ethyl-3-(N-sulfosuccinimidylcarboxy)ethyl Disulfide, Sodium Salt (C21H24N3O9S4Na) is characterized by a flavonoid core, an amide group, a sulfone 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2-(Dansylsulfonamido)ethyl-3-(N-sulfosuccinimidylcarboxy)ethyl Disulfide, Sodium Salt (CAS 1024168-37-3) is a high-purity analytical reference standard with the molecular formula C21H24N3O9S4Na and a molecular weight of 613.66 g/mol.
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), 2-(Dansylsulfonamido)ethyl-3-(N-sulfosuccinimidylcarboxy)ethyl Disulfide, Sodium Salt 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.
