Chemical Structure
Description
The occurrence of 2,3-Diphenylimidazo[1,2-a]pyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,3-Diphenylimidazo[1,2-a]pyridine (CAS 85102-26-7), molecular formula C19H14N2 and molecular weight 270.33 g/mol, is a CATO reference standard with documented purity and traceability.
2,3-Diphenylimidazo[1,2-a]pyridine (C19H14N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. 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.
