Description
Compared with other compounds in its class, the molecular weight of 268.10 g/mol gives 4,4'-Dichloro-2-nitro-1,1'-biphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4,4'-Dichloro-2-nitro-1,1'-biphenyl (CAS 192942-45-3) is a high-purity analytical reference standard with the molecular formula C12H7Cl2NO2 and a molecular weight of 268.10 g/mol.
The molecular framework of 4,4'-Dichloro-2-nitro-1,1'-biphenyl (C12H7Cl2NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
