Dinoprostone (CAS 154170-57-7)/API

Dinoprostone (CAS 154170-57-7) is a high-purity pharmaceutical API classified as a potent uterine contractant, featuring a naturally occurring prostaglandin E2 (PGE2) molecular structure with high affinity for uterine smooth muscle receptors. It exerts targeted effects by stimulating uterine contractions and promoting cervical ripening—mimicking the body’s endogenous prostaglandin activity to facilitate labor induction. Unlike synthetic alternatives, it aligns with physiological labor processes, enhancing safety for both mother and fetus.

Presented as a white to off-white crystalline powder with good solubility in ethanol and water, it supports the development of diverse dosage forms such as gels, suppositories, and vaginal tablets. It caters to the core needs of obstetric pharmaceutical manufacturers, gynecological formulation developers, and clinical supply chains. Widely applied in inducing labor for full-term pregnancies, promoting cervical maturation, and evacuating uterine contents, it aligns with demand for reliable obstetric therapeutic raw materials. Produced under strict GMP standards, each batch undergoes rigorous purity, stability, and bioactivity testing to meet international pharmacopoeia requirements, ensuring consistency for clinical use.
