Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 693.74 g/mol gives DBCO-PEG5-NHS ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
DBCO-PEG5-NHS ester (CAS 2144395-59-3), molecular formula C36H43N3O11 and molecular weight 693.74 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of DBCO-PEG5-NHS ester (C36H43N3O11) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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).
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), DBCO-PEG5-NHS ester 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.
