Suzhou Pharmaceutical Technology Co., Ltd. (China) supplies Crospovidone CAS 9003-39-8 for pharmaceutical B2B procurement — COA, MSDS, and technical documentation available on request.
Crospovidone CAS 9003-39-8, also known as PVPP, cross-linked polyvinylpyrrolidone, cross-linked PVP, and polyvinylpolypyrrolidone, is a water-insoluble polymer excipient supplied by Suzhou Pharmaceutical Technology Co., Ltd. for B2B formulation and process evaluation. We support export supply with COA and MSDS for all shipments, COO for pallet quantities and commercial export orders, and documentation review for buyers in South America, Australia, New Zealand, Mexico, and Canada.
> Product Overview
Crospovidone is a cross-linked N-vinyl-2-pyrrolidone polymer. Because it is insoluble in water and common formulation media, it works through particle structure, swelling behavior, capillary uptake, and adsorption rather than by dissolving into the formulation. Buyers commonly specify Crospovidone by CAS 9003-39-8, PVPP grade, particle-size profile, loss on drying, peroxide value, residual monomer, and microbial limits.
CAS 25249-54-1 may appear in legacy product lists or supplier files connected with polyvinylpyrrolidone chemistry. For this page, CAS 9003-39-8 is the primary identifier for Crospovidone/PVPP, while 25249-54-1 is treated as a related registry reference that should be confirmed against the buyer’s specification before quotation.
> Applications and Technical Reference
In solid dosage development, Crospovidone is selected when a formulation needs a water-insoluble polymeric excipient with strong wicking and swelling behavior. It is also evaluated in granulation, capsule fill blends, dispersible formats, and selected process applications where PVPP adsorption or clarification behavior is useful. The final use level depends on the active ingredient, excipient system, compression conditions, target disintegration profile, and local regulatory requirements.
Technical reference note: PubChem has no direct CID for CAS 9003-39-8, accessed in 2026 (n=0 direct CID result), which is consistent with its polymer identity rather than a single small-molecule structure. This is why a single InChIKey, SMILES string, molecular formula, or molecular weight is not listed as a definitive identifier on this page.
Reference note for formulation teams: a 2018 International Journal of Pharmaceutics review (n=37 excipient and formulation studies reviewed) describes crospovidone as a superdisintegrant evaluated through water uptake, swelling, and tablet disintegration measurements; buyers should still validate performance in their own formula and process.

> Sourcing and Supply Scope
Suzhou Pharmaceutical Technology Co., Ltd. supports Crospovidone sourcing for R&D evaluation, pilot use, and commercial procurement planning. Evaluation and pilot quantities are handled by the Suzhou technical team for specification confirmation and early buyer evaluation. Commercial quantities are planned around 25 kg packaging, pallet quantities, or larger production campaigns after grade, documentation, and packaging requirements are confirmed.
Export support is built around B2B procurement workflows for South America, including Brazil, Argentina, Colombia, Chile, Peru, Ecuador, Bolivia, Paraguay, and Uruguay. We also support buyers in Australia, New Zealand, Mexico, and Canada where documentation and shipment requirements are reviewed before order confirmation.
> Quality and Documentation
Each inquiry starts with a buyer specification or target grade. Our team checks requested test items such as identity, appearance, particle size, loss on drying, pH, peroxide value, residual N-vinyl-2-pyrrolidone, soluble substances, ash, heavy metals, and microbial limits. We do not assume compendial or registration status unless the buyer provides a confirmed requirement and the available batch documentation supports it.
COA and MSDS are available for all Crospovidone shipments. COO is available for pallet quantities and commercial export orders. Additional declarations can be reviewed case by case based on the destination market, buyer quality system, and the documents available for the selected supply route.
> Packaging and Logistics
Standard packaging is selected according to batch size, powder density, and destination requirements. Common options include fiber drums or multilayer bags with inner PE protection. Final packaging, palletization, labels, and shipping marks are confirmed before dispatch. Crospovidone should be stored sealed, dry, and protected from moisture during storage and transit.
> Pricing and Lead Time
Crospovidone pricing depends on grade, particle-size profile, batch quantity, documentation package, packaging format, and destination. For a practical quotation, send the required CAS number, target specification, quantity, destination country, and any document requirements. We will confirm feasibility, lead time, and available batch documentation before issuing a B2B offer.

Yes. Brazil and Argentina are within our regular South America export support scope, subject to destination documentation and freight review.
Can Crospovidone be supplied to Colombia, Chile, or Peru?
Yes. Colombia, Chile, and Peru are supported for B2B Crospovidone inquiries after specification, quantity, and documentation requirements are confirmed.
What is the minimum information needed for a quote?
Please send CAS number, target specification, quantity, destination country, packaging preference, and required documents.
Can particle size be selected for Crospovidone?
Particle-size profile can be discussed by requested D50 and D90 targets, subject to available grade and batch documentation.
How should Crospovidone be stored after receipt?
Keep Crospovidone tightly closed in a cool, dry place and protect it from moisture during storage and handling.
