7-(4-Chlorophenyl)-2-ethyl-[1,2,4]triazolo[1,5-a]pyridine-8-carbonitrile CAS 860611-34-3

Description

The occurrence of 7-(4-Chlorophenyl)-2-ethyl-[1,2,4]triazolo[1,5-a]pyridine-8-carbonitrile 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-(4-Chlorophenyl)-2-ethyl-[1,2,4]triazolo[1,5-a]pyridine-8-carbonitrile (CAS 860611-34-3), molecular formula C15H11ClN4 and molecular weight 282.73 g/mol, is a CATO reference standard with documented purity and traceability.

7-(4-Chlorophenyl)-2-ethyl-[1,2,4]triazolo[1,5-a]pyridine-8-carbonitrile (C15H11ClN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
