Chemical Structure
Description
Owing to a nitrile group, fluorine substitution, an aromatic ring system, 5,6-Difluoropyrazine-2,3-dicarbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.09 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).
5,6-Difluoropyrazine-2,3-dicarbonitrile (CAS 887404-02-6) is a high-purity analytical reference standard with the molecular formula C6F2N4 and a molecular weight of 166.09 g/mol.
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.
As a certified reference material (CRM), 5,6-Difluoropyrazine-2,3-dicarbonitrile 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.
