Chemical Structure

a-Neoendorphin (1-8) (H-4415.0005) CAS 83339-89-3 chemical structure

Description

The molecular framework of a-Neoendorphin (1-8) (H-4415.0005) (C49H70N12O11) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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).

a-Neoendorphin (1-8) (H-4415.0005) (CAS 83339-89-3) is a high-purity analytical reference standard with the molecular formula C49H70N12O11 and a molecular weight of 1003.15 g/mol.

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.
