J. Planar Chromatogr. 33, 669-677 (2020). HPTLC of tris(2-chloroethyl)amine (HN-3) on silica gel with benzene - methanol - triethylamine 425:75:1. Detection by spraying with derivatization reagent (2mg/mL of KMnO4 with 4 mL of H3PO4). The method allowed to study the influence of pH on the degradation of HN-3 and the triethanolamine rate of appearance.
