Description

Gossypetin 3,3‘,8-Trimethylether is a specific, high-purity methylated derivative of the flavonoid gossypetin. This compound is valued for its defined chemical structure, which makes it a crucial reference standard and research chemical in analytical and synthetic chemistry. It is primarily sought by pharmaceutical R&D laboratories, academic research institutions, and specialty chemical manufacturers for use in method development, bioactivity studies, and as a synthetic intermediate.

Application

• Pharmaceutical Reference Standard: Used for the identification, assay, and impurity profiling of related flavonoid compounds in drug development and quality control (QC) laboratories.
• Biochemical Research: Serves as a key intermediate or probe in studying the structure-activity relationships (SAR) of flavonoid derivatives for potential therapeutic applications.
• Analytical Chemistry: Employed as a high-purity calibration standard in chromatographic methods (HPLC, LC-MS) for quantitative analysis in complex matrices.
• Natural Product Synthesis: Acts as a building block or protected intermediate in the semi-synthesis of more complex flavonoid analogs.
• Cosmetic & Nutraceutical Research: Investigated for its potential antioxidant or bioactive properties in advanced formulation development.
