Chemical Structure
Description
Structurally, 2,2-Dimethoxy-5,5-dinitro-1,1-biphenyl (C14H12N2O6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 304.25 g/mol, it falls into the moderately-high-molecular-weight range. 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).
2,2-Dimethoxy-5,5-dinitro-1,1-biphenyl (CAS 81763-59-9) is a high-purity analytical reference standard with the molecular formula C14H12N2O6 and a molecular weight of 304.25 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.
