Description

17,21-Dihydroxypregn-4-Ene-3,11,20-Trione 21-Palmitate is a high-purity steroid derivative, specifically a palmitate ester of a key pregnane intermediate. This compound is of significant value as a crucial building block in the synthesis of more complex steroid-based active pharmaceutical ingredients (APIs). It is primarily needed by research institutions and pharmaceutical manufacturers engaged in the development and production of corticosteroid drugs and other specialized therapeutic agents.

Application

• Pharmaceutical Intermediate: A critical precursor in the multi-step synthesis of potent corticosteroid APIs, such as certain anti-inflammatory agents.
• Steroid Research & Development: Serves as a key reference standard and starting material for medicinal chemistry research focused on novel steroid analogs.
• Biochemical Studies: Used in metabolic pathway studies and enzyme-substrate interaction research due to its specific steroid backbone.
• Process Chemistry: Employed in scale-up and optimization of manufacturing processes for steroid-based pharmaceuticals.

Quality Control

Our 17,21-Dihydroxypregn-4-Ene-3,11,20-Trione 21-Palmitate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency, meeting the stringent requirements for pharmaceutical intermediates. A comprehensive Certificate of Analysis (COA) detailing purity by HPLC, related substances, and other critical parameters is provided with every shipment.

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 material is light-sensitive and easily oxidized; for long-term storage, consideration should be given to maintaining an inert atmosphere (e.g., under nitrogen or argon) to preserve stability.
