Description

5α-Dihydro Testosterone Undecanoate is a long-chain ester derivative of the potent androgen dihydrotestosterone (DHT). This compound is valued for its enhanced lipophilicity and modified pharmacokinetic profile, offering a sustained-release effect compared to its parent hormone. It is primarily utilized in advanced pharmaceutical research and development, particularly in the study of androgen receptor modulation and hormone replacement therapy formulations. Key industries requiring this high-purity intermediate include pharmaceutical manufacturing, biotechnology research, and specialized fine chemical synthesis.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the synthesis of advanced androgen-based therapeutic agents and prodrugs.
• Biomedical Research: Used in preclinical studies to investigate androgen receptor (AR) signaling, tissue selectivity, and metabolic pathways.
• Hormone Replacement Therapy (HRT) Development: Employed in formulating long-acting injectable or transdermal delivery systems for sustained hormonal activity.
• Reference Standard: Acts as a high-purity analytical standard for quality control and method validation in pharmaceutical laboratories.
• Metabolic Studies: Utilized in research focusing on the esterification's impact on hormone half-life, distribution, and clearance.
• Fine Chemical Synthesis: A key starting material for creating novel steroid analogs with tailored biological properties.

Quality Control

Our 5α-Dihydro Testosterone Undecanoate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, identity confirmation by IR and NMR spectroscopy, and residual solvent analysis to ensure it meets exacting standards for research and development. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent degradation from atmospheric humidity. For long-term storage, consider using desiccants.
