Pharmaceutical-Grade Oseltamivir IR Pellets for Immediate-Release Oral Formulations
Oseltamivir IR Pellets are multiparticulate pharmaceutical formulations designed for immediate-release oral dosage applications. The product uses Oseltamivir phosphate as the active ingredient. Oseltamivir phosphate has the CAS Number 204255-11-8, molecular formula C₁₆H₃₁N₂O₈P, and molecular weight 410.40 g/mol.
SDP's pellet product portfolio lists Oseltamivir IR Pellets at 75% strength, providing a high-loading multiparticulate option for pharmaceutical formulation applications.
The immediate-release pellet format is designed to support rapid release of the active ingredient from the multiparticulate system. Final release performance depends on the pellet composition, manufacturing process, particle characteristics and applicable product specification.
Oseltamivir is commonly supplied as Oseltamivir phosphate, the phosphate salt of Oseltamivir. PubChem identifies Oseltamivir phosphate with CAS 204255-11-8, formula C₁₆H₃₁N₂O₈P, and molecular weight 410.40 g/mol.
The free-base form of Oseltamivir is chemically distinct, with CAS 196618-13-0, formula C₁₆H₂₈N₂O₄, and molecular weight 312.40 g/mol. For the pellet product, the applicable active ingredient identity should therefore be specified according to the actual raw material used.
