Description

28-Acetoxyerythrodiol is a high-purity, semi-synthetic triterpenoid derivative, specifically an acetylated form of erythrodiol. This compound is valued as a critical reference standard and advanced intermediate in pharmaceutical and phytochemical research. It is primarily sought by research institutions, analytical laboratories, and fine chemical manufacturers engaged in the development of bioactive compounds, natural product analysis, and metabolic studies.

Application

• Pharmaceutical Reference Standard: Used for the qualitative and quantitative analysis of triterpenoids in drug development and quality control processes.
• Natural Product Research: Serves as a key intermediate or biomarker in the study of plant extracts, particularly from the Oleaceae family (e.g., olive leaf).
• Bioactivity Studies: Employed in pharmacological research to investigate potential anti-inflammatory, antioxidant, or other therapeutic properties of triterpene derivatives.
• Analytical Chemistry: Acts as a calibration standard in chromatographic methods (HPLC, GC) and spectroscopic analysis for method development and validation.
• Fine Chemical Synthesis: Utilized as a building block for the semi-synthesis of more complex triterpenoid analogs with targeted biological activities.
• Cosmeceutical Ingredient Development: Investigated for potential use in high-end skincare formulations due to the bioactive profile of triterpenes.
