The occurrence of N-(5-Iodopyridin-2-yl)acetamide is closely related to an amide group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(5-Iodopyridin-2-yl)acetamide (CAS 66131-78-0), molecular formula C7H7IN2O and molecular weight 262.05 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H7IN2O, N-(5-Iodopyridin-2-yl)acetamide contains an amide group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 262.05 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-(5-Iodopyridin-2-yl)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.
