General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Application

Sodium hydride (60% dispersion in mineral oil) (NaH) can be used for a variety of applications such as:
  • preparation of a plasticizer for the formation of a solid polymer electrolyte (SPE) for optoelectronic application
  • synthesis of heteroaryl thioethers, the common constituents in therapeutic compounds
  • preparation of sodium aluminum hydride (NaAlH4), which can be used as a hydrogen storage material(3)
  • a base and a reducing agent for the deprotonation of alcohols, phenols, amides, ketones, and different functional groups(4)
  • for potential usage in thermal energy storage(5)

Direct intercalation into C60 results in the superconducting material (NaH)4C60.

To investigate the biotransformation pathway of airborne geraniol by Achyranthes bidentata (A. bidentata), deuterium labeled geraniol was applied with or without methyl jasmonate (MeJA), and the biosynthesized metabolites were analyzed. In A. bidentata leaves, geraniol was conjugated with glucose. The conjugate was
