Chemical Structure
Description
The occurrence of H-D-Phe-D-Phe-D-Leu-D-Lys-OH is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
H-D-Phe-D-Phe-D-Leu-D-Lys-OH (CAS CATO-CPTD788746) is a high-purity analytical reference standard with the molecular formula C30H43N5O5 and a molecular weight of 553.69 g/mol.
H-D-Phe-D-Phe-D-Leu-D-Lys-OH (C30H43N5O5) contains a steroid core, 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 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
