Description

17 β-Acetoxy-3-Methoxy-9-Oxo-9,11-Secoestra-1,3,5(10)-Trien-11-Oic Acid is a high-purity, advanced pharmaceutical intermediate derived from the seco-steroid class, specifically engineered for complex synthetic pathways. This compound is valued for its role as a key building block in the research and development of novel therapeutic agents, particularly in the fields of endocrinology and oncology. It is primarily sought by pharmaceutical R&D laboratories, contract manufacturing organizations (CMOs), and academic research institutions engaged in steroid chemistry and drug discovery programs.

Application

• Pharmaceutical Intermediate: A critical precursor in the multi-step synthesis of complex steroid-based active pharmaceutical ingredients (APIs) and investigational new drugs.
• Research & Development: Used in academic and industrial laboratories for exploring new synthetic routes, structure-activity relationships (SAR), and metabolic studies related to seco-steroids.
• Reference Standard: Serves as a high-purity analytical standard for quality control and method development in HPLC, LC-MS, and other chromatographic techniques.
• Biochemical Research: Employed in studies investigating steroid hormone pathways, receptor binding assays, and enzyme inhibition mechanisms.
