N-[6-Amino-1,2,3,4-tetrahydro-1-(2-methylpropyl)-2,4-dioxo-5-pyrimidinyl]-N-butyl-2-chloroacetamide CAS 561009-03-8

Description

N-[6-Amino-1,2,3,4-tetrahydro-1-(2-methylpropyl)-2,4-dioxo-5-pyrimidinyl]-N-butyl-2-chloroacetamide (C14H23ClN4O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

N-[6-Amino-1,2,3,4-tetrahydro-1-(2-methylpropyl)-2,4-dioxo-5-pyrimidinyl]-N-butyl-2-chloroacetamide (CAS 561009-03-8), molecular formula C14H23ClN4O3 and molecular weight 330.81 g/mol, is a CATO reference standard with documented purity and traceability.

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.
