Description

2α,13-Dihydroxy-3β,23-[(1-Methylethylidene)Bis(Oxy)]Urs-11-En-28-Oic Acid 28,13-Lactone is a high-purity, specialized triterpenoid lactone derivative, valued for its role as a critical intermediate in advanced pharmaceutical synthesis and biochemical research. This compound offers researchers and manufacturers a reliable, well-characterized building block for developing novel therapeutic agents, particularly in areas like oncology and metabolic disease. It is essential for B2B clients in the pharmaceutical, biotechnology, and fine chemical sectors who require consistent quality and documented supply chain integrity for their development pipelines.

Application

• Pharmaceutical Intermediate: Serves as a key synthetic precursor for the development of novel triterpenoid-based drug candidates.
• Biochemical Research: Used as a reference standard or probe in studies investigating biological pathways and enzyme interactions.
• Natural Product Synthesis: A crucial building block in the semi-synthesis or total synthesis of complex natural products with potential bioactivity.
• API Development: Employed in the research and development stages of new Active Pharmaceutical Ingredients (APIs), especially within anti-inflammatory or anticancer research.
• Standards and Metrology: Utilized for analytical method development, validation, and as a high-purity calibration standard in quality control laboratories.
