Description

Stigmasterol is a plant-derived sterol of significant commercial and biochemical importance, widely recognized under the identifier CAS NO 83-48-7. It serves as a crucial intermediate in the synthesis of various steroid hormones and vitamin D analogs, offering a sustainable, phytosterol-based alternative to animal-derived cholesterol. This high-purity compound is essential for manufacturers in the pharmaceutical, nutraceutical, and advanced chemical synthesis sectors seeking reliable, high-quality raw materials for their production processes.

Application

• Pharmaceutical Intermediate: A key starting material for the semi-synthesis of vital steroid hormones, including progesterone, corticoids, and vitamin D3.
• Nutraceutical & Functional Food Ingredient: Used in cholesterol-lowering formulations and dietary supplements for its potential cardiovascular benefits.
• Cosmetic & Personal Care: Incorporated into anti-aging and skin-repair formulations for its stabilizing and bioactive properties.
• Biochemical Research: Serves as a standard and reagent in sterol metabolism studies, membrane research, and as a precursor in laboratory-scale organic synthesis.
• Chemical Synthesis: Utilized as a chiral building block for the production of complex organic molecules and fine chemicals.
