Chemical Structure

3,5-Bis(4-fluorophenyl)pyridine CAS 171819-99-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,5-Bis(4-fluorophenyl)pyridine.

3,5-Bis(4-fluorophenyl)pyridine (CAS 171819-99-1), molecular formula C17H11F2N and molecular weight 267.27 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 3,5-Bis(4-fluorophenyl)pyridine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 267.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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

CATO manufactures 3,5-Bis(4-fluorophenyl)pyridine 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.
