Chemical Structure
Description
The molecular framework of 1-(12-(Methacryloyloxy)dodecyl)pyridin-1-ium bromide (C21H34NO2Br) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies 1-(12-(Methacryloyloxy)dodecyl)pyridin-1-ium bromide (CAS 148753-80-4), a certified reference material (molecular formula C21H34NO2Br, MW 412.41 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
