Opis

Zastosowanie

Sodium tert-butoxide may be used as a safe and effective alternative to sodium hydride for the coupling of hydroxyethyl adenine with diethyl p-toluenesulfonyloxymethanephosphonate to form 9-[2-(diethylphosphonomethoxy)ethyl]adenine (diethyl-PMEA), which is a key intermediate to prepare adefovir dipivoxil.
It can also be used:
- To facilitate the coupling of aryl halides with benzene derivatives in the presence of 10-phenanthroline derivative.
- To activate first-row transition-metal pre-catalysts.
- As a base for the amination of aryl chlorides in the presence of a novel palladacyclic precatalyst.
For general uses, product is also available in powdered form (359270)

Cechy i korzyści

ChemBeads are chemical coated glass beads. ChemBeads offer improved flowability and chemical uniformity perfect for automated solid dispensing and high-throughput experimentation. The method of creating ChemBeads uses no other chemicals or surfactants allowing the user to accurately dispense sub-milligram amounts of chemical.
