(S)-2-Amino-N-(4-methyl-2-oxo-2H-chromen-7-yl)-5-ureidopentanamide 2,2,2-trifluoroacetate CAS 201851-46-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-2-Amino-N-(4-methyl-2-oxo-2H-chromen-7-yl)-5-ureidopentanamide 2,2,2-trifluoroacetate.

(S)-2-Amino-N-(4-methyl-2-oxo-2H-chromen-7-yl)-5-ureidopentanamide 2,2,2-trifluoroacetate (CAS 201851-46-9), molecular formula C16H20N4O4C2HF3O2 and molecular weight 446.38 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (S)-2-Amino-N-(4-methyl-2-oxo-2H-chromen-7-yl)-5-ureidopentanamide 2,2,2-trifluoroacetate (C16H20N4O4C2HF3O2) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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).

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.

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.
