CATO supplies 57188-46-2 Bis(p-nitrobenzyl) Phosphorochloridate Phosphorochloridic Acid Bis(p-nitrobenzyl) Ester Phosphorochloridic Acid Bis[(4-nitrophenyl)methyl] Ester p-Nitro-benzyl Alcohol Phosphorochloridate (CAS 57188-46-2), a certified reference material (molecular formula C14H12ClN2O7P, MW 386.68 g/mol) for analytical method development and quality control.

57188-46-2 Bis(p-nitrobenzyl) Phosphorochloridate Phosphorochloridic Acid Bis(p-nitrobenzyl) Ester Phosphorochloridic Acid Bis[(4-nitrophenyl)methyl] Ester p-Nitro-benzyl Alcohol Phosphorochloridate (C14H12ClN2O7P) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
