Description General description May contain varying amounts of anhydride. Application Reactant for preparation of: • Thienylpyridyl garlands via cross-coupling with heteroaryl halides • Arenes via nickel-catalyzed cross-coupling with potassium aryl- and heteroaryl trifluoroborates • Meso-substituted ABCD-type porphyrins by functionalization reactions • Analogs of (acetylamino)(dimethylpyrazol)(pyridyl)pyrimidines as A2A adenosine receptor antagonists for the treatment of Parkinson′s disease • 5-hydroxy-1,3,2-dioxaborolan-4-ones boronate-amine complexes via heterocyclization with α-oxocarboxylic acids followed by subsequent complexation • Radioligands with optimized brain kinetics for PET imaging of nAChR Packaging 1, 5 g in glass bottle
