Compared with other compounds in its class, the molecular weight of 289.11 g/mol gives 3-Ethyl-2-methylbenzoxazolium Iodide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Ethyl-2-methylbenzoxazolium Iodide (CAS 5260-37-7), a certified reference material (molecular formula C10H12NOI, MW 289.11 g/mol) for analytical method development and quality control.
3-Ethyl-2-methylbenzoxazolium Iodide (C10H12NOI) 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, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 3-Ethyl-2-methylbenzoxazolium Iodide 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.
