4-(4-(m-Tolyl)-1H-pyrazol-3-yl)-4H-1,2,4-triazole CAS 62538-00-5

Description

The occurrence of 4-(4-(m-Tolyl)-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-(4-(m-Tolyl)-1H-pyrazol-3-yl)-4H-1,2,4-triazole (CAS 62538-00-5), 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-(4-(m-Tolyl)-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 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.
