Description

Stigmasterol is a plant-derived phytosterol of significant commercial and biochemical importance, widely recognized for its role as a key intermediate in the synthesis of steroid hormones and vitamin D3. Its high purity and consistent quality are critical for ensuring reliable performance in downstream pharmaceutical and nutraceutical manufacturing processes. This compound is essential for suppliers and manufacturers in the pharmaceutical, cosmetic, and dietary supplement industries seeking a reliable, high-grade raw material.

Application

• Pharmaceutical Intermediate: A crucial starting material for the semi-synthesis of various steroid-based drugs, including progesterone, cortisone, and other corticosteroids.
• Nutraceutical Ingredient: Used in dietary supplements and functional foods for its potential cholesterol-lowering properties and as a component of plant sterol blends.
• Cosmetic Formulations: Incorporated into skincare products for its emollient and skin-conditioning benefits.
• Research & Development: Serves as a standard or reagent in biochemical research, particularly in studies of lipid metabolism and membrane biology.
• Chemical Synthesis: Employed as a chiral building block in organic synthesis for creating complex molecular structures.

Quality Control

Our Stigmasterol is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. The product is tested against rigorous in-house specifications, which typically align with industry standards for pharmaceutical intermediates. A comprehensive Certificate of Analysis (COA), detailing purity, identity, and impurity profiles, is provided with each shipment to guarantee supply reliability and quality assurance for your critical processes.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
