1,2-Bis(4-fluorophenyl)ethane-1,2-diamine CAS 1185877-05-7

Description

Compared with other compounds in its class, the molecular weight of 248.27 g/mol gives 1,2-Bis(4-fluorophenyl)ethane-1,2-diamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,2-Bis(4-fluorophenyl)ethane-1,2-diamine (CAS 1185877-05-7), molecular formula C14H14F2N2 and molecular weight 248.27 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 1,2-Bis(4-fluorophenyl)ethane-1,2-diamine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 248.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 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.
