Description

Stigmastanol CAS NO 138126-65-5 is a phytosterol derivative, specifically the saturated form of stigmasterol, known for its role in cholesterol metabolism research. This compound is valued for its use as a key analytical reference standard and as a biochemical tool in nutritional and pharmaceutical studies. It is primarily sought by research institutions, pharmaceutical R&D departments, and manufacturers of dietary supplements and functional foods for investigating cholesterol-lowering mechanisms and developing novel health products.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the quality control and assay development of sterol-based drugs and supplements.
• Nutritional Research: Serves as a critical biochemical reagent in studies investigating the inhibition of dietary cholesterol absorption and its impact on serum lipid profiles.
• Dietary Supplement Formulation: Incorporated as an active ingredient in functional foods and nutraceuticals aimed at supporting cardiovascular health.
• Analytical Chemistry: Employed as an internal standard or calibrant in chromatographic methods (GC, HPLC) for the quantification of plant sterols and stanols in complex matrices.
• Biochemical Pathway Studies: Utilized in metabolic research to elucidate the enzymatic pathways and biological effects of saturated sterols in vitro and in vivo.
• Cosmetic Ingredient: Applied in advanced skincare formulations for its potential stabilizing and skin-barrier enhancing properties.
