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-(4-Fluorophenyl)prop-2-yn-1-one (CAS 54012-23-6) is a high-purity analytical reference standard with the molecular formula C9H5FO and a molecular weight of 148.13 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 1-(4-Fluorophenyl)prop-2-yn-1-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 1-(4-Fluorophenyl)prop-2-yn-1-one 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.
