Description

1,2,15,16-Tetrahydrotanshiquinone is a specialized, high-purity chemical compound belonging to the diterpenoid quinone class, derived from the traditional medicinal herb *Salvia miltiorrhiza* (Danshen). This compound matters as a key intermediate and reference standard for pharmaceutical research and development, particularly in the study of cardiovascular and cerebrovascular therapeutics. It is primarily needed by research institutions, pharmaceutical manufacturers, and fine chemical suppliers engaged in the synthesis of novel active pharmaceutical ingredients (APIs) and the quality control of herbal extracts.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the synthetic pathway for more complex tanshinone analogs and novel drug candidates.
• Biochemical Research: Used as a reference standard in pharmacological studies to investigate mechanisms related to antioxidant, anti-inflammatory, and anti-proliferative activities.
• Analytical Standard: Employed in high-performance liquid chromatography (HPLC) and mass spectrometry (MS) for the qualitative and quantitative analysis of Danshen extracts and related products.
• Nutraceutical Development: Acts as a marker compound for the standardization and quality assurance of premium-grade herbal supplements targeting cardiovascular health.
• Academic Research: Utilized in universities and R&D labs for structure-activity relationship (SAR) studies and the exploration of new therapeutic applications.

Quality Control

Our 1,2,15,16-Tetrahydrotanshiquinone is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, MS), to ensure it meets the stringent requirements for research and development. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting purity, assay, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is easily oxidized; for long-term storage, consider keeping under an inert atmosphere (e.g., nitrogen or argon) to maintain stability and potency.
