Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 266.01 g/mol gives 2-Fluoro-5-iodoisonicotinamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Fluoro-5-iodoisonicotinamide (CAS 1803740-00-2), molecular formula C6H4FIN2O and molecular weight 266.01 g/mol, is a CATO reference standard with documented purity and traceability.
2-Fluoro-5-iodoisonicotinamide (C6H4FIN2O) contains an amide group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
