Chemical Structure
Description
N-(4-fluoro-3-nitrophenyl)-2-(pyridin-2-ylthio)acetamide (CAS 401574-09-2) is a high-purity analytical reference standard with the molecular formula C13H10FN3O3S and a molecular weight of 307.30 g/mol.
N-(4-fluoro-3-nitrophenyl)-2-(pyridin-2-ylthio)acetamide (C13H10FN3O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.
As a certified reference material (CRM), N-(4-fluoro-3-nitrophenyl)-2-(pyridin-2-ylthio)acetamide 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.
