Pyridine anhydrous 99 8%

Pyridine may be used as a base for the conversion of: • Alkyltrichlorosilanes to trimethoxyalkylsilanes which are used as precursors for preparing alkylsilicates • 1-Indanone to 1-indanone oxime which can undergo reductive ring-expansion to form tetrahydroquinoline It may also be used to catalyze the borylation reaction of haloarenes to form arylboronates without using transition metal
