Description

Wilforol A CAS NO 167882-66-8 is a bioactive triterpenoid compound isolated from the traditional medicinal plant *Tripterygium wilfordii* (Thunder God Vine). This high-purity reference standard is critical for pharmaceutical research and development, particularly in the study of natural product-based therapeutics. It is primarily sought by researchers and manufacturers in the pharmaceutical, biotechnology, and nutraceutical industries for its application in anti-inflammatory and immunosuppressive activity studies, as well as for use as an analytical standard in quality control laboratories.

Application

• Pharmaceutical Reference Standard: Serves as a primary standard for the identification, assay, and purity testing of Wilforol A in raw materials and finished products.
• Bioactivity Research: Used in in vitro and in vivo studies to investigate its immunosuppressive, anti-inflammatory, and potential anti-cancer properties.
• Natural Product Extraction & Isolation: Acts as a marker compound for the standardization and quality assessment of extracts derived from *Tripterygium wilfordii*.
• Analytical Method Development: Essential for developing and validating HPLC, LC-MS, and other chromatographic methods in analytical laboratories.
• Preclinical Drug Development: Utilized in early-stage drug discovery programs focusing on novel therapeutic agents from botanical sources.

Quality Control

Our Wilforol A is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity determination and spectroscopic methods (NMR, MS) for structural confirmation, to ensure it meets the high standards required for research and development. A detailed Certificate of Analysis (COA) providing batch-specific data is supplied with every order to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C in a dry environment. For long-term storage, consider storing under an inert atmosphere at -20°C. Allow the product to equilibrate to room temperature before opening to prevent moisture condensation.
