Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Ethyl-2,5,6-trimethylbenzo[d]oxazol-3-ium iodide.
CATO supplies 3-Ethyl-2,5,6-trimethylbenzo[d]oxazol-3-ium iodide (CAS 62509-87-9), a certified reference material (molecular formula C12H16NOI, MW 317.17 g/mol) for analytical method development and quality control.
Structurally, 3-Ethyl-2,5,6-trimethylbenzo[d]oxazol-3-ium iodide (C12H16NOI) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 317.17 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-2,5,6-trimethylbenzo[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.
