Based on its molecular formula C7H11N5O3, 3-((3,5-Dioxo-2,3,4,5-tetrahydro-1,2,4-triazin-6-yl)(methyl)amino)propanamide contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 213.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies 3-((3,5-Dioxo-2,3,4,5-tetrahydro-1,2,4-triazin-6-yl)(methyl)amino)propanamide (CAS 380656-30-4), a certified reference material (molecular formula C7H11N5O3, MW 213.19 g/mol) for analytical method development and quality control.
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.
