> Applications
Remdesivir is used by pharmaceutical and research organizations developing antiviral formulations, reference methods, and impurity-control strategies. API supply is intended for qualified buyers who will confirm dosage form, impurity requirements, pharmacopoeial strategy, and finished-dose registration obligations in their own markets.
Antiviral formulation research
A 2020 NEJM journal article reported a randomized, double-blind, placebo-controlled trial evaluating Remdesivir in hospitalized adults with lower respiratory tract infection (NEJM, doi:10.1056/NEJMoa2007764, n=1063). This supports the need for carefully controlled Remdesivir API quality in antiviral formulation and analytical-development programs.
Analytical and impurity-control development
Buyers typically evaluate assay, chiral or stereochemical purity, related substances, residual solvents, water content, particle properties, and stability behavior before moving from sample quantities to pilot or commercial batches. We supply API only, not finished injections, lyophilized products, oral products, compounded preparations, 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 Remdesivir API. Small batches (up to 10 kg) are produced directly by our technical team in Suzhou. For larger commercial quantities, production is scaled up at qualified manufacturing facilities, with export documentation provided according to the order scope.
- Small-batch orders (≤10 kg): prepared by our technical team in Suzhou. Lead time 10–14 business days from order confirmation.
- Commercial bulk (>10 kg): scaled up at qualified manufacturing facilities. Lead time 14–21 business days depending on batch size and documentation.
We export Remdesivir API to buyers across South America — including Brazil, Argentina, Colombia, Chile, Peru, Ecuador, Bolivia, Paraguay, and Uruguay — as well as to Australia, New Zealand, Mexico, and Canada. Inquiries from European, Middle Eastern, and Asian markets are also welcome.
> Quality & Export Documentation
All Remdesivir shipments are accompanied by a Certificate of Analysis (COA) confirming identity, appearance, assay, and related substances against batch specification.
