Chemical Structure
Description
As a certified reference material (CRM), 6-Methoxy-1-methylquinolin-1-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.
CATO supplies 6-Methoxy-1-methylquinolin-1-ium iodide (CAS 21979-59-9), a certified reference material (molecular formula C11H12NOI, MW 301.12 g/mol) for analytical method development and quality control.
Structurally, 6-Methoxy-1-methylquinolin-1-ium iodide (C11H12NOI) 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 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 301.12 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.
