> Sevelamer API — Overview
Sevelamer (CAS: 52757-95-6, also known as sevelamer hydrochloride, sevelamer carbonate, Renagel active ingredient, Renvela active ingredient, and sevelámero) is a cross-linked poly(allylamine) polymer API material used in phosphate-binding formulation, analytical-development, and research programs where local regulations permit. Suzhou Pharmaceutical Technology Co., Ltd. supplies Sevelamer API material 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
Sevelamer is used by pharmaceutical and research organizations developing phosphate-binding formulations, polymer characterization methods, and impurity-control strategies. API material supply is intended for qualified buyers who will confirm dosage form, salt form, binding-capacity method, residual monomer limits, and finished-dose registration obligations in their own markets.
Phosphate-binding formulation research
A 2002 journal article reported a randomized clinical trial comparing Sevelamer with calcium-based phosphate binders in hemodialysis patients (Kidney International, doi:10.1046/j.1523-1755.2002.00434.x, n=200). This supports the need for carefully controlled Sevelamer polymer quality in phosphate-binding formulation and analytical-development programs.
Polymer characterization and impurity control
Buyers typically evaluate phosphate-binding capacity, residual monomer content, chloride or carbonate form, moisture, particle size distribution, swelling behavior, and stability before moving from sample quantities to pilot or commercial batches. We supply API material only, not finished tablets, powder sachets, 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 Sevelamer API material. 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 Sevelamer API material 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 Sevelamer shipments are accompanied by a Certificate of Analysis (COA) confirming identity, appearance, binding-capacity or assay method, and related quality attributes against batch specification. MSDS is provided for all orders, and Certificate of Origin (COO) is available for commercial bulk shipments.
| Order size | Documentation included |
| ≤10 kg (small-batch / research) | COA + MSDS |
| >10 kg (commercial bulk) | COA + MSDS + COO |
> Packaging & Logistics

Sevelamer API material is shipped with moisture-protective packaging and batch labels matched to the COA. Shipping options include express courier for samples, air freight for kilogram orders, and sea freight for larger commercial shipments where timing allows.
> Pricing & Supply
Sevelamer pricing is provided on request. We do not publish list prices because the final quote depends on order quantity, salt form, binding-capacity requirement, documentation needs, shipping destination, and current raw material costs.
- MOQ: 100 g for qualified buyers
- Sample policy: 10–50 g samples available for analytical confirmation
- Bulk discount tiers apply at 500 g, 1 kg, 5 kg, and 10 kg
- Payment: T/T (bank transfer). 100% in advance for standard orders. Terms for larger repeat orders by arrangement.
