Chemical Structure
Description
8-Chloro-2-(4-methoxyphenyl)imidazo[1,2-a]pyridine (C14H11ClN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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).
8-Chloro-2-(4-methoxyphenyl)imidazo[1,2-a]pyridine (CAS 168837-40-9), molecular formula C14H11ClN2O and molecular weight 258.70 g/mol, is a CATO reference standard with documented purity and traceability.
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.
