Description

10-o-Methylprotosappanin B is a specialized, high-purity phytochemical compound derived from sappan wood (Caesalpinia sappan). This compound matters as a valuable reference standard and active pharmaceutical ingredient (API) intermediate for research and development in the life sciences. It is primarily needed by pharmaceutical R&D laboratories, nutraceutical manufacturers, and academic institutions focusing on natural product chemistry and pharmacological studies.

Application

• Pharmaceutical Reference Standard: Used for the qualitative and quantitative analysis of sappan wood extracts and related formulations in quality control laboratories.
• Bioactive Compound Research: Serves as a key intermediate or target molecule in studies investigating anti-inflammatory, antioxidant, and antimicrobial activities.
• Natural Product Synthesis: Acts as a building block or precursor in the semi-synthesis of more complex homoisoflavonoid derivatives for drug discovery programs.
• Analytical Method Development: Employed as a certified standard to develop and validate HPLC, LC-MS, and other chromatographic methods for phytochemical profiling.
• Nutraceutical Ingredient Standardization: Used to standardize and authenticate botanical dietary supplements containing Caesalpinia sappan extract.
