Description

(+)-Cloprostenol Sodium CAS NO 62561-03-9 is the sodium salt of a potent synthetic prostaglandin analog. This high-purity active pharmaceutical ingredient (API) is critical for its targeted biological activity in veterinary and research applications. It is primarily required by manufacturers in the animal health sector and by research institutions conducting studies in reproductive biology and physiology.

Application

• Veterinary Pharmaceuticals: Key active ingredient in formulations for estrus synchronization and the treatment of reproductive disorders in livestock, particularly cattle and horses.
• Animal Breeding Management: Used to induce parturition (birthing) at a predetermined time, facilitating better herd management and veterinary care.
• Research & Development: A vital tool in biochemical and pharmacological research for studying prostaglandin receptors, signaling pathways, and reproductive endocrinology.
• Veterinary Clinical Practice: Employed by veterinarians for therapeutic termination of pregnancy and treatment of chronic endometritis (pyometra) in small and large animals.
• API Synthesis: Serves as a critical intermediate or starting material for the synthesis of more complex prostaglandin-based compounds.
