Description
As a certified reference material (CRM), 2,3,5,6-Tetrafluorobenzene-1,4-diamine 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.
2,3,5,6-Tetrafluorobenzene-1,4-diamine (CAS 1198-64-7) is a high-purity analytical reference standard with the molecular formula C6H4F4N2 and a molecular weight of 180.10 g/mol.
Owing to a nitrile group, fluorine substitution, an aromatic ring system, 2,3,5,6-Tetrafluorobenzene-1,4-diamine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 180.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
