Description

Tanshinlactone CAS NO 105351-70-0 is a specialized diterpenoid compound, a key constituent derived from the medicinal herb *Salvia miltiorrhiza* (Danshen). This high-purity phytochemical is valued for its role as a critical reference standard and active pharmaceutical ingredient (API) intermediate in advanced research and development. It is essential for manufacturers and research institutions in the pharmaceutical, nutraceutical, and life science sectors focused on cardiovascular and metabolic health solutions.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the quality control and standardization of Danshen extracts and related herbal preparations.
• Active Pharmaceutical Ingredient (API) Intermediate: Serves as a key building block in the synthesis of novel cardioprotective and neuroprotective drug candidates.
• Nutraceutical Formulation: Incorporated into high-end dietary supplements targeting circulatory health and antioxidant support.
• Biomedical Research: Utilized in *in vitro* and *in vivo* studies to investigate mechanisms related to anti-inflammatory, anti-fibrotic, and anti-atherosclerotic activities.
• Analytical Chemistry: Employed as an analytical standard in HPLC, LC-MS, and GC-MS methods for the quantification of diterpenoids in complex matrices.
• Cosmeceutical Development: Explored for potential applications in skincare formulations for its purported antioxidant and anti-aging properties.
