Description

Cryptotanshinone is a key bioactive diterpenoid quinone compound, primarily isolated from the traditional medicinal herb *Salvia miltiorrhiza* (Danshen). It serves as a critical intermediate and reference standard in pharmaceutical research and development. This compound is particularly valued by researchers and manufacturers in the pharmaceutical, nutraceutical, and advanced chemical synthesis sectors for its significant biological activity and structural properties.

Application

• Pharmaceutical R&D: Serves as a high-purity reference standard and active pharmaceutical ingredient (API) intermediate for drug discovery programs.
• Cardiovascular & Metabolic Research: Used in preclinical studies investigating mechanisms related to angiogenesis, atherosclerosis, and metabolic syndrome.
• Oncology Research: Employed as a tool compound in studies targeting cell proliferation, apoptosis, and metastasis pathways.
• Natural Product & Nutraceutical Formulation: Acts as a standardized marker compound for quality control in herbal extracts and dietary supplements derived from Danshen.
• Chemical Synthesis: Functions as a versatile chiral building block for the semi-synthesis of novel tanshinone analogs and complex natural product derivatives.
• Academic & Institutional Research: Utilized in universities and research institutes for pharmacological, biochemical, and phytochemical investigations.

Quality Control

Our Cryptotanshinone is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, identity confirmation via IR and NMR, and residual solvent analysis, to ensure it meets the stringent requirements for research and development. Certificates of Analysis (COA) documenting all specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its sensitivity, the product should be handled under an inert atmosphere when appropriate to minimize oxidation. Keep the container sealed to protect from moisture.
