Chemical Structure
Description
The occurrence of (DPhe12,Nle21,12-41)-Corticotropin Releasing Factor (12-41), human, rat is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(DPhe12,Nle21,12-41)-Corticotropin Releasing Factor (12-41), human, rat (CAS 129133-27-3), molecular formula C158H265N49O43 and molecular weight 3539.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (DPhe12,Nle21,12-41)-Corticotropin Releasing Factor (12-41), human, rat (C158H265N49O43) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
