Description

Danshensu is a bioactive phenolic acid compound derived from the traditional Chinese medicinal herb *Salvia miltiorrhiza* (Danshen). This high-purity ingredient is valued for its significant antioxidant and cardioprotective properties, making it a critical intermediate and active ingredient in advanced research and product development. It is primarily sought by manufacturers in the pharmaceutical, nutraceutical, and cosmetic industries for applications in cardiovascular health supplements, skincare formulations, and as a reference standard for analytical purposes.

Application

• Pharmaceutical Intermediates: Serves as a key starting material or active pharmaceutical ingredient (API) in the synthesis of cardiovascular and neuroprotective drugs.
• Nutraceuticals & Dietary Supplements: Formulated into capsules, tablets, and powders for its potent antioxidant and heart health-supporting benefits.
• Cosmetic & Skincare Actives: Incorporated into anti-aging, brightening, and protective skincare products due to its ability to neutralize free radicals and reduce oxidative stress.
• Biomedical Research: Used as a reference standard in HPLC, LC-MS, and other analytical methods for quality control and pharmacokinetic studies.
• Functional Food & Beverages: Added to health-focused food and drink products to enhance their functional antioxidant profile.
• Veterinary Medicine: Applied in animal health supplements for similar cardioprotective and anti-inflammatory effects.
