Description

Wilforic Acid A CAS NO 193684-74-1 is a bioactive triterpenoid compound isolated from the traditional medicinal plant *Tripterygium wilfordii* (Thunder God Vine). This specific compound is of significant interest for its role as a key chemical marker and active ingredient in botanical extracts and advanced pharmaceutical research. It is primarily sought by manufacturers and researchers in the pharmaceutical, nutraceutical, and phytochemical industries for the development of standardized botanical products and novel therapeutic agents.

Application

• As a reference standard for the quality control and standardization of *Tripterygium wilfordii* (Lei Gong Teng) extracts.
• As a key active pharmaceutical ingredient (API) intermediate in the research and development of new drugs.
• In phytochemical and pharmacological research to study anti-inflammatory, immunosuppressive, and anti-cancer mechanisms.
• For the formulation of high-purity botanical supplements and nutraceuticals targeting immune system modulation.
• As a critical component in analytical method development (e.g., HPLC, LC-MS) for herbal medicine authentication.

Quality Control

Our Wilforic Acid A is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets high-purity standards suitable for research and development. A comprehensive Certificate of Analysis (COA) detailing purity, residual solvents, and heavy metals is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C for long-term stability. This product is hygroscopic (moisture-sensitive); ensure the container is sealed under an inert atmosphere after each use to prevent degradation.
