4-(4-Chloro-3-fluorophenoxy)benzonitrile CAS 449778-68-1

Description

The occurrence of 4-(4-Chloro-3-fluorophenoxy)benzonitrile is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(4-Chloro-3-fluorophenoxy)benzonitrile (CAS 449778-68-1), molecular formula C13H7ClFNO and molecular weight 247.65 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H7ClFNO, 4-(4-Chloro-3-fluorophenoxy)benzonitrile contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 247.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), 4-(4-Chloro-3-fluorophenoxy)benzonitrile 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.
