6,7-Dihydro-[1,2,4]triazolo[1,5-a]pyrimidin-5(4H)-one CAS 35220-35-0

Description

The occurrence of 6,7-Dihydro-[1,2,4]triazolo[1,5-a]pyrimidin-5(4H)-one is closely related to an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6,7-Dihydro-[1,2,4]triazolo[1,5-a]pyrimidin-5(4H)-one (CAS 35220-35-0) is a high-purity analytical reference standard with the molecular formula C5H6N4O and a molecular weight of 138.13 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, 6,7-Dihydro-[1,2,4]triazolo[1,5-a]pyrimidin-5(4H)-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
