Frequent Uses

Analytical Chemistry
It's a key component in Fehling's solution, used to test for the presence of reducing sugars. Also used in the Biuret reagent to measure protein concentration, as it helps maintain cupric ions in solution at an alkaline pH.

Protein Crystallography
Acts as a precipitant in protein crystallography, a technique used to study protein structure.

Piezoelectric Properties
Its ability to generate an electrical charge when stressed (and vice versa) makes it useful in sensors and actuators.

Combustion Accelerator
Used as a combustion accelerator in cigarette paper.
