Description

Danshensu Sodium Salt is the sodium salt form of Danshensu, a key bioactive phenolic acid derived from the traditional Chinese medicinal herb *Salvia miltiorrhiza* (Danshen). This compound is valued for its enhanced solubility and stability in aqueous formulations compared to the free acid, making it a critical intermediate and reference standard for research and development. It is primarily utilized by the pharmaceutical, nutraceutical, and life science industries for applications in cardiovascular research, anti-inflammatory studies, and the development of standardized botanical extracts.

Application

• Pharmaceutical Reference Standard: Used as a high-purity chemical reference substance (CRS) for the quality control and standardization of Danshen extracts and related herbal preparations.
• Active Pharmaceutical Ingredient (API) Intermediate: Serves as a key synthetic intermediate in the production of cardiovascular and neuroprotective drugs.
• Nutraceutical & Dietary Supplement Formulation: Incorporated into supplements targeting antioxidant support and cardiovascular health due to its bioactive properties.
• Biomedical Research: Employed in *in vitro* and *in vivo* studies to investigate mechanisms related to oxidative stress, inflammation, and ischemia-reperfusion injury.
• Cosmeceutical Ingredients: Used in advanced skincare formulations for its potential anti-aging and protective effects against environmental stressors.
