2,6-Dichloro-4-(4-(trifluoromethyl)phenyl)pyridine CAS 697739-21-2

Description

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.

2,6-Dichloro-4-(4-(trifluoromethyl)phenyl)pyridine (CAS 697739-21-2), molecular formula C12H6Cl2F3N and molecular weight 292.08 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 2,6-Dichloro-4-(4-(trifluoromethyl)phenyl)pyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.08 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).

As a certified reference material (CRM), 2,6-Dichloro-4-(4-(trifluoromethyl)phenyl)pyridine 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.
