Chemical Structure

2,3,5,6-Tetrafluoropyridine CAS 2875-18-5 chemical structure

Description

2,3,5,6-Tetrafluoropyridine (C5HF4N) contains a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

2,3,5,6-Tetrafluoropyridine (CAS 2875-18-5) is a high-purity analytical reference standard with the molecular formula C5HF4N and a molecular weight of 151.06 g/mol.

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), 2,3,5,6-Tetrafluoropyridine 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.
