Description

(-)-Egcg-3''-o-Me is a specific, methylated derivative of the prominent green tea catechin, Epigallocatechin gallate (EGCG). This targeted structural modification enhances its metabolic stability and bioavailability compared to its parent compound, making it a valuable tool for advanced research and development. It is primarily sought by researchers and product developers in the pharmaceutical, nutraceutical, and cosmeceutical industries for its potential bioactive properties.

Application

• Pharmaceutical Research: Investigated as a lead compound or reference standard in studies targeting metabolic disorders, inflammation, and oncology due to its enhanced stability profile.
• Nutraceutical Formulation: Used in the development of high-end dietary supplements where improved bioavailability is a critical product differentiator.
• Cosmeceutical Ingredients: Incorporated into advanced skincare formulations for its potential antioxidant and anti-aging properties.
• Biochemical Research: Serves as a precise molecular probe to study the structure-activity relationships (SAR) of catechins and their biological pathways.
• Reference Standard: Employed as a high-purity analytical standard in HPLC, LC-MS, or NMR for quality control and quantification of catechin derivatives in complex matrices.
