3,3'-Dimethoxy-(1,1'-biphenyl)-4,4'-diamine dihydrochloride (CAS 20325-40-0), molecular formula C14H16N2O2HCl and molecular weight 280.75 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3,3'-Dimethoxy-(1,1'-biphenyl)-4,4'-diamine dihydrochloride (C14H16N2O2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 280.75 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
