Chemical Structure

4-(5-Phenyl-1H-tetrazol-1-yl)pyridine CAS 57761-77-0 chemical structure

Description

4-(5-Phenyl-1H-tetrazol-1-yl)pyridine (CAS 57761-77-0), molecular formula C12H9N5 and molecular weight 223.23 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-(5-Phenyl-1H-tetrazol-1-yl)pyridine (C12H9N5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 223.23 g/mol, it falls into the medium-molecular-weight range. 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.

As a certified reference material (CRM), 4-(5-Phenyl-1H-tetrazol-1-yl)pyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
