Chemical Structure
Description
924280-65-9 alpha-[3-(o-Pyridyldisulfido)propanoylamido]-omega-succinimidyl ester dodeca(ethylene glycol) MFCD13185005 (CAS 924280-65-9) is a high-purity analytical reference standard with the molecular formula C39H65N3O17S2 and a molecular weight of 912.07 g/mol.
The molecular framework of 924280-65-9 alpha-[3-(o-Pyridyldisulfido)propanoylamido]-omega-succinimidyl ester dodeca(ethylene glycol) MFCD13185005 (C39H65N3O17S2) is characterized by a nitrogen-containing heterocyclic scaffold, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 924280-65-9 alpha-[3-(o-Pyridyldisulfido)propanoylamido]-omega-succinimidyl ester dodeca(ethylene glycol) MFCD13185005 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.
