Description

β-Sitosterol Sulfate is a sulfated derivative of the widely occurring phytosterol, β-sitosterol, offering enhanced water solubility and distinct biological activity. This modification is crucial for applications requiring improved bioavailability and specific interaction with biological membranes. It serves as a valuable intermediate and active ingredient for research and development in the pharmaceutical, nutraceutical, and cosmetic industries, particularly in areas focused on lipid metabolism and anti-inflammatory formulations.

Application

• Pharmaceutical Intermediates: Used in the synthesis of novel drug candidates targeting cholesterol absorption, inflammation, and prostate health.
• Nutraceutical Research: Investigated as a bioactive component in dietary supplements for its potential lipid-lowering and immune-modulating properties.
• Cosmetic Actives: Incorporated into advanced skincare formulations for its purported soothing and barrier-strengthening effects.
• Biochemical Research: Serves as a standard or reagent in studies of sterol metabolism, membrane biology, and signal transduction pathways.
• Reference Standard: Utilized as a high-purity analytical standard in quality control laboratories for HPLC, LC-MS, or other chromatographic methods.

Quality Control

Our β-Sitosterol Sulfate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identification, assay, and impurity profiling, to ensure it meets high-purity standards suitable for research and industrial use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture.
