Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Fluoro-4-nitrophenyl)piperidin-4-one.
1-(2-Fluoro-4-nitrophenyl)piperidin-4-one (CAS 439097-58-2), molecular formula C11H11FN2O3 and molecular weight 238.22 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2-Fluoro-4-nitrophenyl)piperidin-4-one (C11H11FN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-(2-Fluoro-4-nitrophenyl)piperidin-4-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.
