19(R)-hydroxy PGF1α is primarily used in biomedical research to study prostaglandin pathways and their physiological effects. It serves as a key compound in investigating inflammatory responses, vascular functions, and reproductive processes, particularly in understanding the role of prostaglandins in uterine contractions and labor. Additionally, it is utilized in the development of therapeutic agents targeting prostaglandin-related disorders, such as hypertension, cardiovascular diseases, and inflammatory conditions. Its application also extends to studying ocular pressure regulation, providing insights into glaucoma treatment strategies.
