Descripción
p-Toluenesulfonic acid monohydrate is used as a catalyst in the synthesis of resveratrol, in oxane derivatives as an antimalarial agent, as substituted piperidine and unsymmetrical benzyl. It acts as a catalyst in the preparation of 1,3,5-trisubstituted pyrazoles derivatives, selenated ketene dithioacetals, triazoloquinazolinone and benzimidazoquinazolinone derivatives. It also serves as an intermediate in the esterification and in reductive amination reactions.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
