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.
CATO supplies (E)-3-(4-Bromoanilino)-1-(2,5-dichloro-3-thienyl)-2-propen-1-one (CAS 338402-20-3), a certified reference material (molecular formula C13H8BrCl2NOS, MW 377.08 g/mol) for analytical method development and quality control.
The molecular framework of (E)-3-(4-Bromoanilino)-1-(2,5-dichloro-3-thienyl)-2-propen-1-one (C13H8BrCl2NOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
