Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 837.94 g/mol gives D-Lys-D-Leu-D-Val-D-Phe-D-Phe-D-Ala distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
D-Lys-D-Leu-D-Val-D-Phe-D-Phe-D-Ala (CAS 342877-55-8), molecular formula C38H57N7O7C2HF3O2 and molecular weight 837.94 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of D-Lys-D-Leu-D-Val-D-Phe-D-Phe-D-Ala (C38H57N7O7C2HF3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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.
