Chemical Structure
Description
(Des-Arg9,Leu8)-Bradykinin (CAS 64695-06-3), molecular formula C41H63N11O10 and molecular weight 870.00 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (Des-Arg9,Leu8)-Bradykinin (C41H63N11O10) 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 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 (Des-Arg9,Leu8)-Bradykinin 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.
