23195-63-3 1H-1,2,4-Triazole, 5-(3-pyridyl)- Pyridine, 3-(1H-1,2,4-triazol-5-yl)- 5-(3-Pyridyl)-1H-1,2,4-triazole CAS 23195-63-3

Description

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.

23195-63-3 1H-1,2,4-Triazole, 5-(3-pyridyl)- Pyridine, 3-(1H-1,2,4-triazol-5-yl)- 5-(3-Pyridyl)-1H-1,2,4-triazole (CAS 23195-63-3), molecular formula C7H6N4 and molecular weight 146.15 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H6N4, 23195-63-3 1H-1,2,4-Triazole, 5-(3-pyridyl)- Pyridine, 3-(1H-1,2,4-triazol-5-yl)- 5-(3-Pyridyl)-1H-1,2,4-triazole contains a nitrile group, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 146.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
