Description

Calcium Bis(4-Hydroxybutyrate) CAS NO 82316-97-0 is a calcium salt of 4-hydroxybutyric acid, serving as a stable and bioavailable source of calcium and the GHB precursor. This compound is valued for its role in controlled synthesis and as a nutritional or pharmaceutical intermediate where precise calcium delivery is required. It is primarily needed by manufacturers in the pharmaceutical, nutraceutical, and specialty chemical industries for research, development, and production.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly those related to the central nervous system.
• Nutraceutical Formulations: Acts as a source of bioavailable calcium in dietary supplements and functional food products.
• Biochemical Research: Serves as a precursor or substrate in metabolic pathway studies and enzymatic research.
• Chemical Synthesis: Employed as a building block for the preparation of more complex organic molecules and esters.
• Reference Standard: Used as a high-purity calibration standard in analytical laboratories for quality control and method development.
