Description

Paroxetine CAS NO 61869-08-7 is a potent and selective serotonin reuptake inhibitor (SSRI) belonging to the phenylpiperidine class of compounds. It is a critical active pharmaceutical ingredient (API) valued for its efficacy in managing central nervous system disorders. This high-purity compound is essential for pharmaceutical manufacturers and research institutions developing antidepressant and anti-anxiety medications.

Application

• Pharmaceutical API: Primary use as the active ingredient in the formulation of antidepressant tablets, capsules, and controlled-release dosage forms.
• Generic Drug Manufacturing: Sourcing for the production of generic versions of branded SSRI medications containing paroxetine hydrochloride.
• Clinical Research: Utilization as a reference standard or investigational compound in pharmacological studies and clinical trials.
• Neuropharmacology R&D: Key material for research into serotonin pathways, drug mechanisms of action, and the development of new CNS therapeutics.
• Analytical Testing: Serves as a high-purity standard for quality control laboratories performing HPLC, LC-MS, or spectroscopic assays.
