Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-(2-Fluorophenyl)-5-oxopentanenitrile (CAS 898767-33-4) is a high-purity analytical reference standard with the molecular formula C11H10FNO and a molecular weight of 191.20 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 5-(2-Fluorophenyl)-5-oxopentanenitrile is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 191.20 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), 5-(2-Fluorophenyl)-5-oxopentanenitrile 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.
