General description

2-Amino-5-nitrothiazole(ANT) is a hypoxic radiosensitizing drug. ANT forms square-planar complex, trans-[PdCl2(ANT)2] with palladium in methanol.

Application

2-Amino-5-nitrothiazole was used as diazo component in the synthesis of monoazo disperse dyes. It was used as matrix during matrix-assisted laser desorption/ionization time-of-flight mass spectrometric study of oligonucleotide and protein.
