Quality Control

Our 17β-Hydroxy-5α-Estran-3-One o-(2,4-Dinitrophenyl)Oxime is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and spectroscopic identification (IR, NMR, MS), to ensure it meets exacting standards for research and development. Comprehensive Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from strong oxidizing agents.
