Chemical Structure
Description
CATO supplies 3-Ethyl-2-methyl-5-phenylbenzo[d]oxazol-3-ium iodide (CAS 54919-49-2), a certified reference material (molecular formula C16H16NOI, MW 365.21 g/mol) for analytical method development and quality control.
The molecular framework of 3-Ethyl-2-methyl-5-phenylbenzo[d]oxazol-3-ium iodide (C16H16NOI) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 3-Ethyl-2-methyl-5-phenylbenzo[d]oxazol-3-ium 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.
