Description

Testosterone Palmitate is a long-chain fatty acid ester derivative of the primary male sex hormone, testosterone. This chemical modification enhances the compound's lipophilicity, which is a critical property for specific pharmaceutical and research applications. It is primarily utilized by manufacturers in the pharmaceutical and biotechnology sectors for the development of long-acting hormonal formulations and as a key intermediate in advanced steroid synthesis. The product is supplied under the identifier CAS NO 991-20-8.

Application

• Pharmaceutical Intermediates: Serves as a crucial building block in the synthesis of advanced steroid-based active pharmaceutical ingredients (APIs).
• Long-Acting Hormone Delivery Systems: Used in the research and development of depot formulations, such as injectable oils or implants, due to its lipophilic nature for sustained release.
• Biochemical Research: Employed as a reference standard or reagent in studies investigating androgen receptor binding, metabolism, and hormone stability.
• Veterinary Pharmaceuticals: Applied in the formulation of long-acting anabolic agents for therapeutic use in livestock and companion animals.
• Controlled-Release Studies: Acts as a model compound in pharmacokinetic research to study the absorption and release profiles of esterified hormones from various matrices.
