About Curcumine, 99%

Curcumine (CAS 458-37-7) is a bioactive small molecule offered by Vaqora Chemicals with a typical assay of ≥99%. Formula C21H20O6, molecular weight 368.4 g/mol. Systematically, it is named (1E,6E)-1,7-bis(4-hydroxy-3-methoxyphenyl)hepta-1,6-diene-3,5-dione. Common synonyms include Diferuloylmethane and Diferulylmethane.

The material typically appears as an orange solid. Reported physical data include a melting point of 183-188 °C. Store in a tightly closed container in a cool, dry and well-ventilated place. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

It is commonly used for cell signalling research, pharmacological screening, target validation and indicator for titrations. It is used across academic and industrial research and diagnostics and biotechnology.

Standard pack sizes are 5 g, 10 g, 100 g and 250 g, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
