Chemical Structure
Description
As a certified reference material (CRM), 2-Fluoro-5-nitro-DL-phenylalanine 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.
2-Fluoro-5-nitro-DL-phenylalanine (CAS 1259997-48-2), molecular formula C9H9FN2O4 and molecular weight 228.18 g/mol, is a CATO reference standard with documented purity and traceability.
2-Fluoro-5-nitro-DL-phenylalanine (C9H9FN2O4) 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
