Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1032.20 g/mol gives Lys-[Des-Arg9]-Bradykinin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Lys-[Des-Arg9]-Bradykinin (CAS 71800-36-7), a certified reference material (molecular formula C50H73N13O11, MW 1032.20 g/mol) for analytical method development and quality control.
The molecular framework of Lys-[Des-Arg9]-Bradykinin (C50H73N13O11) 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).
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.
As a certified reference material (CRM), Lys-[Des-Arg9]-Bradykinin 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.
