Chemical Structure
Description
CATO manufactures 1-Ethyl-1-methyl-4-oxopiperidin-1-ium iodide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 1-Ethyl-1-methyl-4-oxopiperidin-1-ium iodide (CAS 77542-18-8), a certified reference material (molecular formula C8H16NOI, MW 269.12 g/mol) for analytical method development and quality control.
The molecular framework of 1-Ethyl-1-methyl-4-oxopiperidin-1-ium iodide (C8H16NOI) 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. 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.
