Application:	• Perrhenic acid solution (HReO₄) can be used in dehydrations of oximes, amides, and urea. • HReO₄ can also catalyze azeotropic dehydration of syn- or anti-aldoximes to yield corresponding nitriles. • In combination with tertiary arsines, it gives a versatile catalytic system for epoxidation of alkenes with hydrogen peroxide.
Application:	It is also used to prepare highly conducting and superconducting synthetic metals.
Packaging:	5, 25 g in poly bottle
