Description

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.

4-{[(E)-2-[4-cyano-3-(methylsulfanyl)-1,2-thiazol-5-yl]ethenyl]amino}benzoic acid (CAS 338751-12-5) is a high-purity analytical reference standard with the molecular formula C14H11N3O2S2 and a molecular weight of 317.39 g/mol.

Based on its molecular formula C14H11N3O2S2, 4-{[(E)-2-[4-cyano-3-(methylsulfanyl)-1,2-thiazol-5-yl]ethenyl]amino}benzoic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 317.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
