Chemical Structure

H-Ile-Arg-Pro-OH CAS 149756-66-1 chemical structure

Description

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.

H-Ile-Arg-Pro-OH (CAS 149756-66-1), molecular formula C17H32N6O4 and molecular weight 384.47 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C17H32N6O4, H-Ile-Arg-Pro-OH contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 384.47 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
