Description

Methyltanshinonate CAS NO 135355-72-5 is a high-purity, specialized chemical compound derived from the traditional Chinese medicinal herb *Salvia miltiorrhiza* (Danshen). This compound is valued for its role as a key intermediate and reference standard in advanced pharmaceutical research and development. It is primarily sought by research institutions and pharmaceutical companies focused on cardiovascular, anti-inflammatory, and neuroprotective therapeutic agents.

Application

• Pharmaceutical Reference Standard: Used for the qualitative and quantitative analysis of Danshen-derived products and formulations in quality control laboratories.
• Biochemical Research: Serves as a critical intermediate or probe in studying biological pathways related to oxidative stress and inflammation.
• Natural Product Synthesis: Acts as a building block or target molecule in the semi-synthesis of novel bioactive compounds.
• Nutraceutical Development: Employed in the research and standardization of high-end herbal supplements targeting cardiovascular health.
• Academic Research: Utilized in university and institutional labs for pharmacological screening and mechanistic studies.
