Chemical Structure
Description
CATO supplies 5-Iodo-3,4-dimethylisoxazole (CAS 61314-41-8), a certified reference material (molecular formula C5H6INO, MW 223.01 g/mol) for analytical method development and quality control.
The molecular framework of 5-Iodo-3,4-dimethylisoxazole (C5H6INO) is characterized by an amide group, a hydroxyl group, an ether linkage, iodine substitution. 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.
As a certified reference material (CRM), 5-Iodo-3,4-dimethylisoxazole 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.
