5-Ethoxy-[1,2,4]triazolo[4,3-a]quinoline CAS 54971-01-6

Description

The occurrence of 5-Ethoxy-[1,2,4]triazolo[4,3-a]quinoline is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Ethoxy-[1,2,4]triazolo[4,3-a]quinoline (CAS 54971-01-6) is a high-purity analytical reference standard with the molecular formula C12H11N3O and a molecular weight of 213.24 g/mol.

Structurally, 5-Ethoxy-[1,2,4]triazolo[4,3-a]quinoline (C12H11N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 213.24 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

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.
