Description

Pratensein CAS NO 2284-31-3 is a bioactive isoflavone compound, a key marker and active constituent found in red clover (*Trifolium pratense*). This high-purity phytochemical is valued for its role in research and development within the nutraceutical and pharmaceutical sectors. It is primarily sought by manufacturers and R&D laboratories focused on botanical extracts, women's health supplements, and metabolic research.

Application

• As a reference standard for the quality control and standardization of red clover extracts and related botanical products.
• As a key active pharmaceutical ingredient (API) intermediate in the development of nutraceuticals targeting menopausal symptom support.
• In cosmeceutical formulations for its potential skin-soothing and antioxidant properties.
• For scientific research into phytoestrogens, their mechanisms of action, and metabolic pathways.
• As a dietary supplement ingredient in capsules, tablets, and liquid formulations.
• In the development of functional foods and beverages fortified with bioactive isoflavones.
