H-L-Phe-L-Phe-D-Leu-γ-Pip-OH CAS CATO-CPTD788743

Description

The occurrence of H-L-Phe-L-Phe-D-Leu-γ-Pip-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-L-Phe-L-Phe-D-Leu-γ-Pip-OH (CAS CATO-CPTD788743), molecular formula C30H41N5O5 and molecular weight 551.68 g/mol, is a CATO reference standard with documented purity and traceability.

H-L-Phe-L-Phe-D-Leu-γ-Pip-OH (C30H41N5O5) 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).

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.

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.
