Description

Urofollitropin CAS NO 26995-91-5 is a highly purified preparation of follicle-stimulating hormone (FSH) derived from the urine of postmenopausal women. This biologically active glycoprotein is critical for stimulating follicular growth and maturation in the ovaries. It is an essential active pharmaceutical ingredient (API) for manufacturers of fertility treatments and advanced biopharmaceuticals targeting reproductive health.

Application

• Fertility Drug Formulation: Primary API in injectable medications used for controlled ovarian stimulation in assisted reproductive technology (ART), including in vitro fertilization (IVF).
• Anovulation Treatment: Key therapeutic agent in drugs prescribed for the treatment of anovulatory infertility in women.
• Biopharmaceutical Research: Used as a reference standard and critical reagent in R&D for developing novel reproductive health therapies and diagnostic assays.
• Hormone Replacement Therapy (HRT) Components: Employed in the development of complex hormonal formulations for specific clinical indications.
• Veterinary Pharmaceuticals: Applied in fertility treatments for livestock and other animals in veterinary medicine.
