Chemical Structure

n-(6-Amino-1-butyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)-2-chloro-n-(2-methoxyethyl)propanamide CAS 1050883-98-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 346.81 g/mol gives n-(6-Amino-1-butyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)-2-chloro-n-(2-methoxyethyl)propanamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

n-(6-Amino-1-butyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)-2-chloro-n-(2-methoxyethyl)propanamide (CAS 1050883-98-1) is a high-purity analytical reference standard with the molecular formula C14H23ClN4O4 and a molecular weight of 346.81 g/mol.

The molecular framework of n-(6-Amino-1-butyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)-2-chloro-n-(2-methoxyethyl)propanamide (C14H23ClN4O4) 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.

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.
