Chemical Structure

5-(3-Pyridyl)-1H-tetrazole CAS 3250-74-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 147.14 g/mol gives 5-(3-Pyridyl)-1H-tetrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-(3-Pyridyl)-1H-tetrazole (CAS 3250-74-6) is a high-purity analytical reference standard with the molecular formula C6H5N5 and a molecular weight of 147.14 g/mol.

The molecular framework of 5-(3-Pyridyl)-1H-tetrazole (C6H5N5) is characterized by a nitrile group, an aromatic ring system. 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).

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.
