Compared with other compounds in its class, the molecular weight of 277.06 g/mol gives 2-Iodo-4-methoxybenzamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Iodo-4-methoxybenzamide (CAS 1369864-41-4), molecular formula C8H8INO2 and molecular weight 277.06 g/mol, is a CATO reference standard with documented purity and traceability.
2-Iodo-4-methoxybenzamide (C8H8INO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution. 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), 2-Iodo-4-methoxybenzamide 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.
