Description

Tanshinol B CAS NO 189290-30-0 is a high-purity, bioactive chemical compound derived from the traditional Chinese medicinal herb *Salvia miltiorrhiza* (Danshen). This compound is valued for its significant potential in pharmaceutical research and development, particularly in the study of cardiovascular and cerebrovascular health. It serves as a critical reference standard and active pharmaceutical ingredient (API) intermediate for manufacturers and research institutions focused on creating novel therapeutic agents. Its unique chemical structure makes it a subject of interest for advanced pharmacological studies.

Application

• As a primary reference standard for the quality control and quantification of Danshen extracts and related herbal products in analytical laboratories.
• As a key active pharmaceutical ingredient (API) intermediate in the research and development of cardiovascular and neuroprotective drugs.
• In pharmacological and biochemical research to study mechanisms related to antioxidant activity, anti-inflammatory effects, and blood circulation improvement.
• For the formulation development of nutraceuticals and functional foods aimed at supporting circulatory health.
• As a chemical marker in the standardization and authentication of *Salvia miltiorrhiza* raw materials and finished products.
• In academic and institutional research exploring the structure-activity relationships of natural phenolic acids.
