(E)-3-methyl-1-(3-oxo-3-(p-tolyl)prop-1-en-1-yl)pyridin-1-ium chloride CAS 19518-27-5

Description

The occurrence of (E)-3-methyl-1-(3-oxo-3-(p-tolyl)prop-1-en-1-yl)pyridin-1-ium chloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(E)-3-methyl-1-(3-oxo-3-(p-tolyl)prop-1-en-1-yl)pyridin-1-ium chloride (CAS 19518-27-5), molecular formula C16H16NOCl and molecular weight 273.76 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H16NOCl, (E)-3-methyl-1-(3-oxo-3-(p-tolyl)prop-1-en-1-yl)pyridin-1-ium chloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 273.76 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
