[1,2,4]Triazolo[4,3-a]quinazoline CAS 235-17-6

Description

Compared with other compounds in its class, the molecular weight of 170.17 g/mol gives [1,2,4]Triazolo[4,3-a]quinazoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

[1,2,4]Triazolo[4,3-a]quinazoline (CAS 235-17-6), molecular formula C9H6N4 and molecular weight 170.17 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of [1,2,4]Triazolo[4,3-a]quinazoline (C9H6N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
