2,4-Dichloro-5-nitropyridine (CAS 4487-56-3) is a high-purity analytical reference standard with the molecular formula C5H2Cl2N2O2 and a molecular weight of 192.99 g/mol.
2,4-Dichloro-5-nitropyridine (C5H2Cl2N2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
