Description

Racdidemethyl Citalopram Hydrochloride CAS NO 1189694-81-2 is a high-purity pharmaceutical intermediate and reference standard. This compound is critical for research and development in neuropharmacology, serving as a key building block or analytical marker. It is primarily required by pharmaceutical R&D laboratories, analytical testing facilities, and manufacturers of active pharmaceutical ingredients (APIs) for quality control and synthesis pathways.

Application

• Pharmaceutical Reference Standard: Used for analytical method development, validation, and quality control testing of citalopram and related enantiomers in API manufacturing.
• Chemical Intermediate: Serves as a precursor in the research-scale synthesis of novel serotonin reuptake inhibitor (SRI) compounds and for studying structure-activity relationships.
• Metabolite Studies: Employed in pharmacokinetic and metabolic pathway research to understand the biotransformation of citalopram and its derivatives.
• Impurity Profiling: Essential for identifying and quantifying process-related impurities and degradation products in citalopram hydrochloride batches.
• Academic & Clinical Research: Utilized in university and institutional labs for neuroscience research and preclinical studies targeting the serotonin transporter.
