(E)-3-methyl-1-(3-oxo-3-phenylprop-1-en-1-yl)pyridin-1-ium chloride CAS 19518-26-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-3-methyl-1-(3-oxo-3-phenylprop-1-en-1-yl)pyridin-1-ium chloride.

CATO supplies (E)-3-methyl-1-(3-oxo-3-phenylprop-1-en-1-yl)pyridin-1-ium chloride (CAS 19518-26-4), a certified reference material (molecular formula C15H14NOCl, MW 259.73 g/mol) for analytical method development and quality control.

The molecular framework of (E)-3-methyl-1-(3-oxo-3-phenylprop-1-en-1-yl)pyridin-1-ium chloride (C15H14NOCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
