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.
3-(Pyridin-4-yl)-6,7-dihydro-5H-pyrrolo[2,1-c][1,2,4]triazole (CAS 114722-58-6) is a high-purity analytical reference standard with the molecular formula C10H10N4 and a molecular weight of 186.21 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 3-(Pyridin-4-yl)-6,7-dihydro-5H-pyrrolo[2,1-c][1,2,4]triazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 186.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
