Chemical Structure

4-(5-Methyl-4-phenyl-1H-pyrazol-3-yl)-4H-1,2,4-triazole CAS 62537-94-4 chemical structure

Description

The occurrence of 4-(5-Methyl-4-phenyl-1H-pyrazol-3-yl)-4H-1,2,4-triazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(5-Methyl-4-phenyl-1H-pyrazol-3-yl)-4H-1,2,4-triazole (CAS 62537-94-4), molecular formula C12H11N5 and molecular weight 225.25 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-(5-Methyl-4-phenyl-1H-pyrazol-3-yl)-4H-1,2,4-triazole (C12H11N5) 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.

As a certified reference material (CRM), 4-(5-Methyl-4-phenyl-1H-pyrazol-3-yl)-4H-1,2,4-triazole 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.
