5,7-Dioxo-6,7-dihydro-2H-[1,2,3]triazolo[4,5-d]pyrimidin-4(5H)-yl acetate CAS 34618-17-2

Description

Compared with other compounds in its class, the molecular weight of 211.13 g/mol gives 5,7-Dioxo-6,7-dihydro-2H-[1,2,3]triazolo[4,5-d]pyrimidin-4(5H)-yl acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5,7-Dioxo-6,7-dihydro-2H-[1,2,3]triazolo[4,5-d]pyrimidin-4(5H)-yl acetate (CAS 34618-17-2), molecular formula C6H5N5O4 and molecular weight 211.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5,7-Dioxo-6,7-dihydro-2H-[1,2,3]triazolo[4,5-d]pyrimidin-4(5H)-yl acetate (C6H5N5O4) 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.
