Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 300.31 g/mol gives Methyl 5-ethyl-7-(3-hydroxyphenyl)-4,7-dihydro-[1,2,4]triazolo[1,5-a]pyrimidine-6-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl 5-ethyl-7-(3-hydroxyphenyl)-4,7-dihydro-[1,2,4]triazolo[1,5-a]pyrimidine-6-carboxylate (CAS 879935-79-2) is a high-purity analytical reference standard with the molecular formula C15H16N4O3 and a molecular weight of 300.31 g/mol.
The molecular framework of Methyl 5-ethyl-7-(3-hydroxyphenyl)-4,7-dihydro-[1,2,4]triazolo[1,5-a]pyrimidine-6-carboxylate (C15H16N4O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
