About Curcumine, ≥94% (curcuminoid content), ≥80% (curcumin)

Curcumine is a bioactive small molecule carrying the CAS registry number 458-37-7, specified at ≥80% purity. Formula C21H20O6, molecular weight 368.4 g/mol. The IUPAC name is (1E,6E)-1,7-bis(4-hydroxy-3-methoxyphenyl)hepta-1,6-diene-3,5-dione. It is also known as Diferuloylmethane or Diferulylmethane.

The material typically appears as a yellow to orange powder. Reported physical data include a melting point of 175 °C. Store it at 2–8 °C, in a tightly closed container. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Typical applications include cell signalling research, pharmacological screening, target validation and indicator for titrations. Buyers come mainly from academic and industrial research and diagnostics and biotechnology.

We offer Curcumine in 500 mg, 1 g and 25 g packs with a batch-specific COA, and ship to customers worldwide.
