6-Amino-5-bromo-2-thioxo-2,3-dihydropyrimidine-4-carbonitrile (CAS 2106640-62-2) is a high-purity analytical reference standard with the molecular formula C5H3BrN4S and a molecular weight of 231.07 g/mol.
The molecular framework of 6-Amino-5-bromo-2-thioxo-2,3-dihydropyrimidine-4-carbonitrile (C5H3BrN4S) is characterized by a nitrile group, sulfur-containing functionality, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
