Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-Ethyl-4-(6-fluoropyridin-2-yl)piperazine (CAS 1251093-50-1) is a high-purity analytical reference standard with the molecular formula C11H16FN3 and a molecular weight of 209.26 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 1-Ethyl-4-(6-fluoropyridin-2-yl)piperazine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 209.26 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), 1-Ethyl-4-(6-fluoropyridin-2-yl)piperazine 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.
