Chemical Structure

H-Pro-Glu-OH CAS 67644-00-2 chemical structure

Description

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.

H-Pro-Glu-OH (CAS 67644-00-2), molecular formula C10H16N2O5 and molecular weight 244.24 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H16N2O5, H-Pro-Glu-OH contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 244.24 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).

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.
