Description

15,16-Dihydrotanshindiol C is a bioactive diterpenoid compound, a key intermediate and reference standard derived from the medicinal plant *Salvia miltiorrhiza* (Danshen). This high-purity compound is essential for pharmaceutical research and development, particularly in the study of cardiovascular and cerebrovascular therapeutics. It is primarily utilized by research institutions, pharmaceutical companies, and manufacturers of high-value botanical extracts and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Reference Standard: Used for the qualitative and quantitative analysis of Danshen extracts and related pharmaceutical preparations.
• Biochemical Research: Serves as a critical tool for studying the pharmacological mechanisms, metabolic pathways, and structure-activity relationships of tanshinone derivatives.
• Active Pharmaceutical Ingredient (API) Intermediate: Employed in the synthesis and development of novel drug candidates targeting cardiovascular diseases.
• Quality Control for Herbal Extracts: Acts as a marker compound to standardize and authenticate the quality and potency of commercial Danshen extracts.
• Academic Research: Utilized in university and institutional labs for pharmacological screening and natural product chemistry studies.
