Description

Demethoxycurcumin is a bioactive curcuminoid compound, a key constituent of turmeric (Curcuma longa). This high-purity ingredient is valued for its potent biological activity, often exhibiting enhanced stability and bioavailability compared to curcumin in certain applications. It is primarily sought by manufacturers in the nutraceutical, pharmaceutical, and cosmetic industries for advanced formulation development. Our supply of Demethoxycurcumin CAS NO 22608-11-3 ensures consistent quality for research and commercial production.

Application

• Nutraceutical & Dietary Supplements: Used as a key active ingredient in formulations targeting inflammation, oxidative stress, and joint health.
• Pharmaceutical Research: Serves as a reference standard and active pharmaceutical ingredient (API) intermediate in drug discovery for its anti-inflammatory and anticancer properties.
• Cosmetics & Skincare: Incorporated into serums and creams for its antioxidant and skin-brightening effects.
• Functional Food & Beverages: Added to health-focused products as a natural bioactive colorant and functional component.
• Biochemical Research: Utilized in vitro and in vivo studies to investigate cell signaling pathways related to chronic diseases.
• Anti-Aging Formulations: Applied in cosmeceutical products designed to protect against environmental skin damage.
