Description

Norbiogest CAS NO 51367-42-1 is a high-purity synthetic progestogen compound, also known as Norgestomet, widely recognized for its potent hormonal activity. This compound is critical for applications requiring precise biological control and reproductive management in veterinary and pharmaceutical research. It serves as an essential active pharmaceutical ingredient (API) and intermediate for manufacturers in the animal health, veterinary medicine, and life science sectors.

Application

• Veterinary Pharmaceutical Synthesis: Primary use as the key active ingredient in hormonal implants and injections for estrus synchronization and fertility control in livestock, particularly cattle.
• Animal Reproduction Management: Formulation into controlled-release devices for timed artificial insemination (TAI) programs to improve breeding efficiency.
• Research & Development: Utilized as a reference standard and biochemical tool in endocrinology and reproductive biology research within academic and industrial laboratories.
• API Manufacturing: Serves as a critical intermediate and starting material for the synthesis of more complex steroidal pharmaceuticals.
• Veterinary Drug Formulation: Incorporated into topical gels, subcutaneous implants, and intramuscular injectable solutions.
