Chemical Structure

1-Methyl-3-phenyl-1H-1,2,4-triazole CAS 39696-58-7 chemical structure

Description

1-Methyl-3-phenyl-1H-1,2,4-triazole (CAS 39696-58-7), molecular formula C9H9N3 and molecular weight 159.19 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-Methyl-3-phenyl-1H-1,2,4-triazole (C9H9N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 159.19 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
