Potassium carbonate is an inorganic base. It participates as a base in the palladacycle catalyzed Heck reaction of chlorobenzene with styrene. Addition of amino acids (glycine, sarcosine and proline) to K₂CO₃ (solvent) promotes the absorption of CO₂.

Potassium carbonate has been used in the preparation of disulfonated bis[4-(3-aminophenoxy)phenyl]sulfone, a disulfonated diamine monomer.

It may be used in the following studies:

• As a reagent in the synthesis of polysubstituted iodobenzene derivatives.
• As a base for the synthesis of high molecular weight homopolymers and copolymers derived from various bisphenols.
• As a base for the Suzuki coupling of aryl halides with aryl boronic acids.
• The Heck reaction of styrene and bromobenzene.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.

For general uses, product is also available in powdered form (209619)
