Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 199.17 g/mol gives Pyrimidin-2-ylmethanamineoxalate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Pyrimidin-2-ylmethanamineoxalate (CAS 866625-10-7) is a high-purity analytical reference standard with the molecular formula C5H7N3C2H2O4 and a molecular weight of 199.17 g/mol.
The molecular framework of Pyrimidin-2-ylmethanamineoxalate (C5H7N3C2H2O4) is characterized by an amino-acid-derived structure, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
