Chemical Structure
Description
1-Chloro-2-methyl-3,4-dinitrobenzene (C7H5ClN2O4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
1-Chloro-2-methyl-3,4-dinitrobenzene (CAS 290353-56-9) is a high-purity analytical reference standard with the molecular formula C7H5ClN2O4 and a molecular weight of 216.58 g/mol.
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.
