Chemical Structure
Description
CATO supplies Arg-Arg-Lys-Ala-Ser-Gly-Pro-Pro-Val (CAS 93511-94-5), a certified reference material (molecular formula C41H74N16O11, MW 967.13 g/mol) for analytical method development and quality control.
Arg-Arg-Lys-Ala-Ser-Gly-Pro-Pro-Val (C41H74N16O11) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Arg-Arg-Lys-Ala-Ser-Gly-Pro-Pro-Val 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.
