Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Fluorophenoxy)-2,4-dinitrobenzene.
1-(4-Fluorophenoxy)-2,4-dinitrobenzene (CAS 1033-02-9), molecular formula C12H7FN2O5 and molecular weight 278.19 g/mol, is a CATO reference standard with documented purity and traceability.
1-(4-Fluorophenoxy)-2,4-dinitrobenzene (C12H7FN2O5) 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. 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.
As a certified reference material (CRM), 1-(4-Fluorophenoxy)-2,4-dinitrobenzene 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.
