Chemical Structure

4,4'-Bi-4H-1,2,4-triazole CAS 16227-15-9 chemical structure

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.

CATO supplies 4,4'-Bi-4H-1,2,4-triazole (CAS 16227-15-9), a certified reference material (molecular formula C4H4N6, MW 136.11 g/mol) for analytical method development and quality control.

Structurally, 4,4'-Bi-4H-1,2,4-triazole (C4H4N6) contains a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 136.11 g/mol, it falls into the low-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.
