Description

Diethylstilbestrol Monophosphate is a phosphate ester derivative of the synthetic estrogen diethylstilbestrol, designed to enhance solubility and bioavailability. This compound is critical for pharmaceutical research and development, particularly in the study of hormone-responsive systems and targeted drug delivery mechanisms. It serves as a key intermediate and reference standard for researchers and manufacturers in the pharmaceutical, biotechnology, and life science sectors requiring high-purity, well-characterized active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: Serves as a crucial precursor in the synthesis of specialized hormonal therapies and prodrug formulations.
• Biochemical Research: Used as a reference standard and tool compound in endocrinology and oncology research to study estrogen receptor interactions.
• Analytical Standard: Employed in quality control laboratories for method development, validation, and calibration in HPLC and LC-MS analyses.
• Prodrug Development: Investigated for its potential in creating targeted delivery systems due to its modified phosphate ester structure.
• Veterinary Pharmaceutical Research: Applied in studies related to animal health and reproductive biology.

Quality Control

Our Diethylstilbestrol Monophosphate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing including identification (IR, NMR), purity assay (HPLC), and control of specified impurities to ensure it meets high-grade standards suitable for research and development. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability, consistency, and compliance with your project requirements.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
