Description

Citalopram is a high-purity active pharmaceutical ingredient (API) belonging to the selective serotonin reuptake inhibitor (SSRI) class. It is a critical compound for the development and manufacturing of antidepressant medications, ensuring therapeutic efficacy and batch-to-batch consistency. This product is essential for pharmaceutical manufacturers, research institutions, and fine chemical suppliers serving the global mental health therapeutics market. Citalopram CAS NO 59729-33-8 is supplied under stringent quality control protocols.

Application

• Pharmaceutical API: Primary active ingredient in the formulation of antidepressant tablets, capsules, and oral solutions.
• Reference Standard: Used as a certified reference material (CRM) in analytical laboratories for method development, validation, and quality control testing.
• Clinical Research: Serves as a key material in preclinical and clinical studies for investigating new therapeutic applications or formulations.
• Generic Drug Manufacturing: Critical for the production of bioequivalent generic versions of SSRI-based medications.
• Chemical Intermediate: Utilized in the synthesis of more complex pharmaceutical compounds or for derivative studies.

Quality Control

Our Citalopram is manufactured and tested in facilities adhering to cGMP (current Good Manufacturing Practice) guidelines. Each batch undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, to ensure it meets stringent pharmacopeial standards such as USP and EP. A detailed Certificate of Analysis (COA) documenting purity, identity, and residual solvents is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a low-humidity environment to prevent moisture absorption and degradation.
