Description

(±)-Cloprostenol Sodium Salt is a synthetic prostaglandin analog of the F2α series, widely recognized for its potent luteolytic and smooth muscle-contracting properties. This high-purity active pharmaceutical ingredient (API) is critical for ensuring precise biological activity and formulation stability in veterinary and research applications. It is primarily utilized by manufacturers in the animal health industry and by research institutions focused on reproductive physiology.

Application

• Veterinary Pharmaceuticals: As the active ingredient in injectable solutions for estrus synchronization and the treatment of reproductive disorders in livestock, such as cattle and swine.
• Animal Breeding Management: For the controlled induction of parturition (birthing) and termination of pregnancy in various domestic animal species.
• Biomedical Research: As a critical research tool for studying prostaglandin receptor (FP receptor) function, uterine contractility, and corpus luteum regression in experimental models.
• API Formulation: Serves as a key starting material or intermediate for compounding pharmacies and manufacturers developing proprietary veterinary therapeutic products.
