Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Chloro-N-(2-oxo-1-propyl-1,2-dihydropyrimidin-4-yl)acetamide.
2-Chloro-N-(2-oxo-1-propyl-1,2-dihydropyrimidin-4-yl)acetamide (CAS 61671-74-7), molecular formula C9H12ClN3O2 and molecular weight 229.66 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Chloro-N-(2-oxo-1-propyl-1,2-dihydropyrimidin-4-yl)acetamide (C9H12ClN3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
