Description

Pueroside B CAS NO 100692-54-4 is a high-purity, naturally derived isoflavone glycoside compound. This specialized phytochemical is valued for its role as a key reference standard and active ingredient in advanced research and development. It is primarily sought by professionals in the pharmaceutical, nutraceutical, and life science sectors for applications in metabolic and pharmacological studies, as well as in the formulation of high-end botanical extracts.

Application

• Pharmaceutical Reference Standard: Used for the qualitative and quantitative analysis of Pueraria lobata (Kudzu) extracts and related products in pharmacopoeial testing and method development.
• Bioactivity & Mechanism Research: Serves as a critical compound in in vitro and in vivo studies investigating metabolic pathways, estrogenic activity, and neuroprotective effects.
• Nutraceutical Ingredient: Incorporated into high-purity botanical supplements targeting menopausal health, cardiovascular support, and blood sugar management.
• Cosmeceutical Formulations: Utilized in advanced skincare products for its potential antioxidant and skin-brightening properties.
• Chemical Synthesis Intermediate: Acts as a starting material or precursor for the semi-synthesis of novel isoflavone derivatives with enhanced bioactivity.
• Quality Control & Authentication: Essential for HPLC and LC-MS analysis to authenticate Kudzu root extracts and ensure product consistency and adulterant-free status.
