Description

[(24S,25S)-24-(β-D-Glucopyranosyloxy)-2α-hydroxyspirost-5-en-3β-yl]4-O-[2-O-(β-D-glucopyranosyl)-3-O-[4-O-(β-D-glucopyranosyl)-β-D-xylopyranosyl]-β-D-glucopyranosyl]-β-D-galactopyranoside is a high-purity, complex steroidal saponin glycoside of significant interest in advanced biochemical research and development. This compound matters as a critical reference standard and intermediate for pharmaceutical discovery, particularly in the study of bioactive natural products and their synthetic analogs. It is primarily needed by research institutions, pharmaceutical R&D laboratories, and manufacturers of high-value nutraceuticals focusing on cardiac glycoside pathways and steroid biosynthesis.

Application

• Pharmaceutical Reference Standard: Used as a certified primary standard for the quality control and assay development of steroidal saponin-based drugs and botanical extracts.
• Biochemical Research: Serves as a key substrate or inhibitor in enzymatic studies related to glycosidase and steroid metabolism.
• Natural Product Synthesis: Acts as a sophisticated chiral building block or target molecule for the semi-synthesis of novel therapeutic agents.
• Analytical Method Development: Employed in calibrating HPLC, LC-MS, and NMR systems for the precise identification and quantification of complex glycosides in mixtures.
• Nutraceutical Standardization: Used to standardize and authenticate high-end botanical supplements derived from plants like fenugreek or Tribulus terrestris.
• Academic Research: Facilitates studies in phytochemistry, structure-activity relationships (SAR), and the biosynthesis of plant secondary metabolites.
