Chemical Structure
Description
(D-Leu7)-LHRH trifluoroacetate salt (CAS 53728-75-9), molecular formula C55H75N17O13C2HF3O2 and molecular weight 1296.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (D-Leu7)-LHRH trifluoroacetate salt (C55H75N17O13C2HF3O2) 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 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 (D-Leu7)-LHRH trifluoroacetate salt 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.
