Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(4-Methoxystyryl)-1-methylquinolin-1-ium iodide.
4-(4-Methoxystyryl)-1-methylquinolin-1-ium iodide (CAS 104816-89-9), molecular formula C19H18NOI and molecular weight 403.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(4-Methoxystyryl)-1-methylquinolin-1-ium iodide (C19H18NOI) is characterized by a steroid core, 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
