Description

Brassicasterol is a naturally occurring phytosterol, a member of the steroid alcohol family with the CAS registry number 474-67-9. This compound is valued for its role as a key biomarker in environmental and food science, as well as its potential applications in nutritional and pharmaceutical research. It is primarily sought by industries focused on analytical standards, nutraceutical development, and advanced biochemical synthesis. Our supply ensures high purity and batch-to-batch consistency for critical research and manufacturing processes.

Application

• Analytical Reference Standard: Used as a certified standard in gas chromatography (GC) and high-performance liquid chromatography (HPLC) for the quantification of sterols in oils, fats, and environmental samples.
• Nutraceutical & Functional Food Research: Investigated for its potential cholesterol-lowering and anti-inflammatory properties as a component of plant sterol blends.
• Pharmaceutical Intermediate: Serves as a starting material or intermediate in the synthesis of more complex steroid-based active pharmaceutical ingredients (APIs).
• Biomarker in Geochemistry: Acts as a specific biomarker for tracing algal and marine organic matter in sediments and petroleum studies.
• Cosmetic Ingredient Research: Explored for use in skincare formulations for its potential stabilizing and bioactive properties.
• Food Quality & Authenticity Control: Employed in methods to authenticate vegetable oils (like canola and rapeseed oil) and detect adulteration.
