Chemical Structure
Description
As a certified reference material (CRM), 1-(5-Iodopyridin-3-yl)ethan-1-one 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.
1-(5-Iodopyridin-3-yl)ethan-1-one (CAS 2355052-46-7), molecular formula C7H6INO and molecular weight 247.03 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(5-Iodopyridin-3-yl)ethan-1-one (C7H6INO) is characterized by an amide group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
