Chemical Structure
Description
As a certified reference material (CRM), [β-Asp5]-Desmopressin 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.
CATO supplies [β-Asp5]-Desmopressin (CAS CATO-C4X-221527), a certified reference material (molecular formula C46H63N13O13S2, MW 1070.20 g/mol) for analytical method development and quality control.
The molecular framework of [β-Asp5]-Desmopressin (C46H63N13O13S2) 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.
