General description

Sodium bromide is a brominating agent mainly used in organic synthetic reactions as a bromide source.

Application

Sodium bromide can be used as:
  • A catalyst to synthesize tetrahydrobenzo[b]pyrans via three-component cyclocondensation of aryl aldehydes, alkyl nitriles, and dimedone under solvent-free and microwave-assisted reactions.
  • A precursor to synthesize bromomethylated γ-lactones via an electrochemical process.
  • A sodium bromide bath to prepare small Ag nanocubes with sharp edges.

Glucose sensors are potentially useful tools for monitoring the glucose concentration in cell culture medium. Here, we present a new, low-cost, and reproducible sensor based on a cellulose-based material, 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) oxidized-cellulose nanocrystals (CNCs). This novel biocompatible and inert nanomaterial
