Thermo Scientific Chemicals Lawesson's Reagent, 97%
Supplier: Thermo Scientific Chemicals A1453006
Description
Lawesson's reagent is a thiation agent used to convert carbonyl compounds into thiocarbonyls. It is also used to thionate enones, esters, lactones, amides, lactams and quinones. Further, it is used to prepare thiols from alcohols. It is associated with silver perchlorate and utilized as and oxophilic Lewis acid catalyst for Diels-Alder reaction of dienes with alfa, beta-unsaturated aldehydes.
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.
