H-Phe-Leu-Glu-Glu-Val-OH CAS 61037-79-4

Description

Compared with other compounds in its class, the molecular weight of 635.71 g/mol gives H-Phe-Leu-Glu-Glu-Val-OH distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies H-Phe-Leu-Glu-Glu-Val-OH (CAS 61037-79-4), a certified reference material (molecular formula C30H45N5O10, MW 635.71 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, H-Phe-Leu-Glu-Glu-Val-OH is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 635.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
