Description

Delta 9,11-Canrenone is a key pharmaceutical intermediate and reference standard, identified by CAS NO 95716-71-5. This compound is of significant importance in the synthesis and quality control of steroidal active pharmaceutical ingredients (APIs). It is primarily required by pharmaceutical manufacturers and research institutions engaged in the development and production of cardiovascular and diuretic medications.

Application

• Pharmaceutical Intermediate: A critical building block in the synthesis of steroidal drugs, particularly canrenone and related potassium-sparing diuretics.
• Reference Standard: Used as a certified reference material (CRM) for analytical method development, validation, and quality control testing in pharmaceutical laboratories.
• Metabolite Studies: Employed in pharmacokinetic and metabolic pathway research for related therapeutic agents.
• Impurity Standard: Serves as a specified impurity standard to monitor and control the quality of bulk drug substances and finished dosage forms.
• Research & Development: Utilized in academic and industrial R&D for exploring new chemical entities and biological activities within the steroid class.
