3-{5-[(2E)-3-(4-chlorophenyl)prop-2-enoyl]-4-methyl-1,3-thiazol-2-yl}-1-methylpyridin-1-ium iodide CAS 477712-99-5

Description

CATO supplies 3-{5-[(2E)-3-(4-chlorophenyl)prop-2-enoyl]-4-methyl-1,3-thiazol-2-yl}-1-methylpyridin-1-ium iodide (CAS 477712-99-5), a certified reference material (molecular formula C19H16ClN2OSI, MW 482.76 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/iodine substitution, 3-{5-[(2E)-3-(4-chlorophenyl)prop-2-enoyl]-4-methyl-1,3-thiazol-2-yl}-1-methylpyridin-1-ium iodide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 482.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
