7-Chloro-5-(2-chlorophenyl)-1-methyl-[1,2,4]triazolo[4,3-a]quinoline CAS 54196-60-0

Description

The occurrence of 7-Chloro-5-(2-chlorophenyl)-1-methyl-[1,2,4]triazolo[4,3-a]quinoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Chloro-5-(2-chlorophenyl)-1-methyl-[1,2,4]triazolo[4,3-a]quinoline (CAS 54196-60-0) is a high-purity analytical reference standard with the molecular formula C17H11Cl2N3 and a molecular weight of 328.20 g/mol.

Structurally, 7-Chloro-5-(2-chlorophenyl)-1-methyl-[1,2,4]triazolo[4,3-a]quinoline (C17H11Cl2N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 328.20 g/mol, it falls into the moderately-high-molecular-weight range. 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.

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.
