Description

Campesterol is a naturally occurring phytosterol, a plant-derived compound structurally similar to cholesterol. It is a key intermediate in the synthesis of vitamin D2 and other valuable steroid compounds, offering significant value in pharmaceutical and nutraceutical development. This high-purity ingredient is essential for manufacturers in the pharmaceutical, dietary supplement, and advanced research sectors seeking reliable, quality-controlled raw materials.

Application

• Pharmaceutical Intermediate: Critical starting material for the semi-synthesis of vitamin D2 (ergocalciferol) and other steroid-based APIs.
• Nutraceutical & Dietary Supplements: Used as a bioactive component in cholesterol-lowering and cardiovascular health formulations.
• Reference Standard: Serves as a certified reference material (CRM) for analytical method development and quality control in food and pharmaceutical testing laboratories.
• Biochemical Research: Utilized in studies of sterol metabolism, membrane biology, and plant biochemistry.
• Cosmeceuticals: Incorporated into skincare products for its stabilizing and bioactive properties.
• Food Fortification: An additive for functional foods aimed at promoting heart health.
