> Applications
Croscarmellose Sodium is evaluated by formulation, excipient-screening, tablet, capsule, powder-blend, and process-development teams that need a cross-linked cellulose polymer. PubChem has no direct CID for CAS 74811-65-7, accessed in 2026 (n=0 direct CID result), which is consistent with its polymer identity; buyers should confirm grade, substitution, swelling behavior, residual salts, particle size, documentation, and intended market requirements before order confirmation.
Cross-linked polymer identity
Croscarmellose Sodium is commonly considered where swelling, water uptake, blend behavior, powder flow, or process performance must be evaluated. Typical specification discussions include appearance, identity, degree of substitution, pH, loss on drying, sodium chloride, sodium glycolate, water-soluble substances, settling volume, and particle size.
Grade and process fit
Different projects may require standard or fine grades, different particle profiles, or residual-salt limits depending on processing route and target product category. Our team confirms the available grade and test items against the buyer’s application before quotation.
