302798-54-5 (Leu31,Pro34)-Neuropeptide Y (13-36) (human, rat) MFCD00672463 (CAS 302798-54-5) is a high-purity analytical reference standard with the molecular formula C134H206N40O35S and a molecular weight of 2969.38 g/mol.
The molecular framework of 302798-54-5 (Leu31,Pro34)-Neuropeptide Y (13-36) (human, rat) MFCD00672463 (C134H206N40O35S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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).
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.
