Product Characteristics

Carbetocin (CAS 37025-55-1) delivers cost-effective perinatal hemorrhage control with single-dose long-acting administration, eliminating repeated dosing and monitoring costs. Although its unit price is higher than conventional oxytocin, it significantly reduces postpartum hemorrhage rates, transfusions, and emergency expenses, offering superior overall cost efficiency. It is an economical and high-performance raw material for preventing atonic bleeding after cesarean section. As a reliable product from China Carbetocin suppliers, we ensure stable pricing and quality.

As a long-acting oxytocin analog, this API is mainly indicated for elective cesarean sections. A single intravenous injection provides strong and sustained uterine rhythmic contraction to prevent postpartum hemorrhage. Clinically proven to reduce bleeding risk by 48% and decrease additional uterotonic use, it improves obstetric safety and delivery quality, making it an essential core API in obstetrics and gynecology.

Supported by large-scale polypeptide synthesis and purification, Carbetocin Raw Material features stable pricing and uniform batches, balancing high quality and economy. Compared with imported brands, our Carbetocin made in China offers outstanding cost performance. We support large packaging and customized specifications, with fast delivery and long-term supply to meet bulk procurement needs of pharmaceutical companies, CDMOs, and research institutions. Carbetocin in stock is available for prompt order fulfillment.
In addition to postpartum hemorrhage prevention, Carbetocin Powder can be used for auxiliary treatment of uterine involution and placental retention, as well as reproductive pharmacological research. Characterized by long action, low dosage, and high safety, its single-dose administration simplifies clinical workflows. It demonstrates significant value in maternal health, emergency pharmacy, and new drug R&D, making it a preferred high-value polypeptide API. We also support Customized Carbetocin for special R&D and production needs.
Full-Cycle Quality Control & Consistent Quality
Quality is the cornerstone of safety and efficacy for raw materials. From raw material input to finished product delivery, Carbetocin production follows standardized full-cycle quality management. Strict standards are implemented across all stages, ensuring long-term stable and reliable product quality and solid support for formulation manufacturing and clinical applications.
A full-cycle quality control system covers raw materials, synthesis, refining, and packaging. Key control points are set for each procedure, with strict testing and release protocols to eliminate quality risks at the source and ensure compliance with pharmaceutical-grade requirements. Every batch of Carbetocin API is fully traceable and meets international regulatory demands.
Through comprehensive in-process testing and stability studies, we continuously monitor purity, impurity profiles, and physicochemical properties, effectively minimizing batch-to-batch variation. This guarantees highly consistent quality among different batches and maintains reliable performance over the long term. Our Carbetocin Raw Material remains stable in purity and performance throughout its shelf life.
Adhering to continuous quality improvement, we optimize processes based on production data and quality control experience. We maintain stable quality in large-scale supply and provide customers with trustworthy and traceable high-grade Carbetocin Powder. As a professional China Carbetocin factory, we uphold strict quality systems for global clients.
Application Scenarios
As a long-acting synthetic oxytocin analog, Carbetocin (CAS 37025-55-1) is widely used in obstetric clinics, pharmaceutical manufacturing, and R&D thanks to its clear pharmacological effects and stable quality. It precisely matches core demands in various scenarios, providing all-round reliable support for perinatal health, pharmaceutical production, and drug innovation.

It is mainly used clinically after cesarean section: a single intravenous injection delivers strong and sustained uterine contraction to prevent atonic postpartum hemorrhage. This simplifies clinical operations, reduces hemorrhage and complication risks, and builds a strong defense for maternal and infant safety. Carbetocin API is widely adopted in global obstetric clinical practices.
It also suits postpartum care for high-risk patients after vaginal delivery, including those with multiple pregnancies, placenta previa, or uterine atony. It rapidly induces uterine contraction, reduces additional uterotonic use, improves postpartum care efficiency, and promotes uterine involution and maternal recovery. Our Carbetocin in stock supports timely clinical and production demands.
In pharmaceutical manufacturing, it serves as a key raw material for producing Carbetocin injection and other finished products. Compliant with major international pharmacopoeia standards, its stable quality ensures consistent formulation production and meets large-scale manufacturing requirements.
