4,4’-Diamino-2,2’-difluorobiphenyl CAS 316-64-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4’-Diamino-2,2’-difluorobiphenyl.

CATO supplies 4,4’-Diamino-2,2’-difluorobiphenyl (CAS 316-64-3), a certified reference material (molecular formula C12H10F2N2, MW 220.22 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 4,4’-Diamino-2,2’-difluorobiphenyl is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 220.22 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.

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.

CATO manufactures 4,4’-Diamino-2,2’-difluorobiphenyl under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
