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.
N2-[[5-(Diphenylmethyl)-2-furanyl]carbonyl]-L-Arginine hydrate (CAS 945254-73-9), molecular formula C24H26N4O4 and molecular weight 434.49 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N2-[[5-(Diphenylmethyl)-2-furanyl]carbonyl]-L-Arginine hydrate (C24H26N4O4) is characterized by a flavonoid core, 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 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.
