Description

19-Norprogesterone is a synthetic progestin steroid, a key intermediate in the synthesis of more complex steroidal pharmaceuticals. This compound matters for its role as a versatile building block in the research and development of novel therapeutic agents, particularly in the field of endocrinology. It is primarily needed by pharmaceutical R&D laboratories, fine chemical manufacturers, and academic institutions engaged in steroid chemistry and hormone-related studies. Our supply ensures high purity and batch-to-batch consistency critical for sensitive synthetic pathways.

Application

• Pharmaceutical Intermediate: Serves as a crucial precursor in the synthesis of advanced progestins and other steroidal active pharmaceutical ingredients (APIs).
• Biochemical Research: Used in studies investigating progesterone receptor binding, activity, and the development of receptor modulators.
• Reference Standard: Employed as an analytical standard in quality control laboratories for method development and validation in steroid analysis.
• Academic & R&D: A fundamental compound for teaching and exploring steroid synthesis routes and structure-activity relationships (SAR) in university and industrial research settings.

Quality Control

Our 19-Norprogesterone is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets high-grade specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption. Keep away from incompatible materials.
