Description

The occurrence of Imidazo[1,5-a][1,3,5]triazin-4(1H)-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.

Imidazo[1,5-a][1,3,5]triazin-4(1H)-one (CAS 145837-60-1), molecular formula C5H4N4O and molecular weight 136.11 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Imidazo[1,5-a][1,3,5]triazin-4(1H)-one (C5H4N4O) contains an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 136.11 g/mol, it falls into the low-molecular-weight range. 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.
