Risperidone

Risperidone (CAS 106266-06-2) is an atypical antipsychotic active pharmaceutical ingredient used in the manufacture of finished-dose psychiatric medications. As a controlled API, it is sourced by pharmaceutical manufacturers and contract formulators for integration into regulated drug products.

Risperidone is the active ingredient in oral solid-dose formulations, including tablets and oral solutions, indicated for schizophrenia and bipolar disorder treatment. Risperdal Consta represents a distinct extended-release injectable microsphere formulation.

This specific application requires specialized excipient systems and cold-chain handling that procurement teams must account for during sourcing. Generic pharmaceutical manufacturers source the API to produce bioequivalent products following patent expiry.

This makes the compound an active target for ANDA and generic dossier development. Contract development and manufacturing organizations also use it as a reference compound in formulation feasibility and dissolution testing programs.

The material is supplied as a white to off-white crystalline powder. It is available in pharmaceutical-grade specifications conforming to USP, BP, and Ph. Eur. monographs for global compliance.

Documentation packages typically include CoA, DMF references, and ICH-compliant impurity profiles. Quantities range from research-scale grams to commercial multi-kilogram batches depending on supplier capability and production requirements.
