Description

2H-Pyran-4-Acetic Acid, 2-(β-D-Glucopyranosyloxy)-3,4-Dihydro-3-(2-Hydroxyethylidene)-5-(Methoxycarbonyl)-, 2-(3,4-Dihydroxyphenyl)Ethyl Ester, (2S,3E,4S)- is a complex, high-purity glycosylated phenolic ester compound of significant interest in advanced research and development. This molecule matters for its unique structural features, combining a glucopyranosyl moiety with a dihydropyran core and a caffeic acid-derived ester, which are often associated with specific biological activities. It is primarily needed by pharmaceutical R&D teams, nutraceutical formulators, and academic researchers working on bioactive natural product derivatives, enzyme inhibitors, or novel therapeutic agents.

Application

• Pharmaceutical Intermediate: Serves as a key synthetic building block or precursor for the development of novel active pharmaceutical ingredients (APIs), particularly in metabolic or neurological disorder research.
• Biochemical Research: Used as a reference standard or probe compound in enzymatic studies, receptor binding assays, and metabolic pathway analysis due to its glycosylated phenolic structure.
• Nutraceutical & Cosmetic Actives: Investigated for potential application in high-end nutraceutical formulations or cosmetic active ingredients targeting antioxidant and skin-beneficial properties.
• Natural Product Synthesis: Acts as an intermediate in the semi-synthesis or total synthesis of complex natural products and their analogs for structure-activity relationship (SAR) studies.
• Analytical Standard: Employed as a high-purity certified reference material (CRM) for quality control and analytical method development in related product manufacturing.
