Pyr-His-Trp-Ser-Tyr-Trp-Leu-Arg-Pro-Gly-NH2 CAS CATO-C4X-186229

Description

The occurrence of Pyr-His-Trp-Ser-Tyr-Trp-Leu-Arg-Pro-Gly-NH2 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.

CATO supplies Pyr-His-Trp-Ser-Tyr-Trp-Leu-Arg-Pro-Gly-NH2 (CAS CATO-C4X-186229), a certified reference material (molecular formula C64H82N18O13, MW 1311.45 g/mol) for analytical method development and quality control.

Structurally, Pyr-His-Trp-Ser-Tyr-Trp-Leu-Arg-Pro-Gly-NH2 (C64H82N18O13) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 33.0, corresponding to approximately 33 ring(s) or double-bond equivalent(s). With a molecular weight of 1311.45 g/mol, it falls into the high-molecular-weight range. 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.
