rel-(1S,2S)-1,2-Bis(4-fluorophenyl)ethane-1,2-diamine CAS 105469-16-7

Description

The occurrence of rel-(1S,2S)-1,2-Bis(4-fluorophenyl)ethane-1,2-diamine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

rel-(1S,2S)-1,2-Bis(4-fluorophenyl)ethane-1,2-diamine (CAS 105469-16-7) is a high-purity analytical reference standard with the molecular formula C14H14F2N2 and a molecular weight of 248.27 g/mol.

rel-(1S,2S)-1,2-Bis(4-fluorophenyl)ethane-1,2-diamine (C14H14F2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), rel-(1S,2S)-1,2-Bis(4-fluorophenyl)ethane-1,2-diamine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
