6-((2-Aminoethyl)amino)-5-chloropyrimidine-2,4(1H,3H)-dione CAS 399549-96-3

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.

6-((2-Aminoethyl)amino)-5-chloropyrimidine-2,4(1H,3H)-dione (CAS 399549-96-3), molecular formula C6H9ClN4O2 and molecular weight 204.61 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-((2-Aminoethyl)amino)-5-chloropyrimidine-2,4(1H,3H)-dione (C6H9ClN4O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
