Escitalopram oxalate

Escitalopram oxalate (CAS 219861-08-2) is the salt form of the S-enantiomer of citalopram, supplied as a pharmaceutical active ingredient for antidepressant drug manufacturing.

Known under the development code Lu 26-054-0, it is the active pharmaceutical ingredient (API) behind a broad class of branded and generic SSRI formulations worldwide.

The primary use is in the manufacture of finished oral dosage forms, such as tablets and film-coated tablets, targeting major depressive disorder and generalized anxiety disorder.

Generic drug manufacturers source it as the API for direct compression or wet granulation tablet production. Contract development and manufacturing organizations incorporate it into reference standard batches.

Regulatory submissions for generic market entry in the US, EU, and other regulated markets require documentation of API sourcing, making supplier qualification a critical procurement step.

Escitalopram oxalate is supplied as a white to off-white crystalline powder. It is available in USP, BP, and Ph. Eur. compendial grades to meet the requirements of regulated pharmaceutical markets.

Quantities range from reference-standard milligram quantities through multi-kilogram commercial API batches, with ICH-compliant documentation typically expected for global distribution.
