Description
As a certified reference material (CRM), 1-(3-Ethynyl-4-fluorophenyl)ethan-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.
1-(3-Ethynyl-4-fluorophenyl)ethan-1-one (CAS 1233513-11-5), molecular formula C10H7FO and molecular weight 162.16 g/mol, is a CATO reference standard with documented purity and traceability.
1-(3-Ethynyl-4-fluorophenyl)ethan-1-one (C10H7FO) contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
