Chemical Structure

4H,5H,6H,7H-[1,2,3,4]Tetrazolo[1,5-a]pyrimidine CAS 803739-51-7 chemical structure

Description

The molecular framework of 4H,5H,6H,7H-[1,2,3,4]Tetrazolo[1,5-a]pyrimidine (C4H7N5) is characterized by 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).

CATO supplies 4H,5H,6H,7H-[1,2,3,4]Tetrazolo[1,5-a]pyrimidine (CAS 803739-51-7), a certified reference material (molecular formula C4H7N5, MW 125.13 g/mol) for analytical method development and quality control.

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.
