> Milrinone API — Overview
Milrinone (CAS: 78415-72-2, also known as Primacor active ingredient, PDE3 inhibitor API, bipyridine inotrope API, milrinoneum, and 1,6-dihydro-2-methyl-6-oxo-3,4-bipyridine-5-carbonitrile) is a PDE3 inhibitor API used in cardiovascular formulation, analytical-development, and research programs where local regulations permit. Suzhou Pharmaceutical Technology Co., Ltd. supplies Milrinone API in controlled small-batch and bulk quantities from Suzhou, China, with export to South America, Australia, New Zealand, Mexico, Canada, and worldwide markets. Export documentation: COA and MSDS standard for all orders.

> Applications
Milrinone is used by pharmaceutical and research organizations developing PDE3 inhibitor formulations, reference methods, and impurity-control strategies. API supply is intended for qualified buyers who will confirm dosage form, solid-state form, assay method, particle-size needs, impurity requirements, pharmacopoeial approach, and finished-dose registration obligations in their own markets.
PDE3 inhibitor formulation research
A 2002 JAMA journal article reported the OPTIME-CHF randomized controlled trial evaluating short-term intravenous milrinone in controlled cardiovascular research (JAMA, doi:10.1001/jama.287.12.1541, n=949). This supports the need for carefully controlled Milrinone API quality in PDE3 inhibitor formulation and analytical-development programs.
Analytical and impurity-control development
Buyers typically evaluate assay, related substances, residual solvents, water content, identity, solid-state form, particle-size distribution, microbial limits, and stability behavior before moving from sample quantities to pilot or commercial batches. We supply API only, not finished tablets, capsules, oral liquids, compounded products, or branded medicines.
> Sourcing & Supply
Suzhou Pharmaceutical Technology Co., Ltd. is an R&D-driven pharmaceutical company with in-house synthesis and analytical capability for Milrinone API.
