For pharmaceutical researchers and chemical manufacturers, understanding the intricate details of chemical intermediates is fundamental to successful drug development. 3-Oxo Citalopram, designated by CAS number 372941-54-3, stands out as a critical intermediate in the synthesis of Citalopram, a prominent Selective Serotonin Reuptake Inhibitor (SSRI) used globally for treating depression and anxiety.

The compound's chemical identity is defined by its molecular formula, C20H19FN2O2, and a molecular weight of approximately 338.38 g/mol. Its physical presentation is often described as a pale yellow gel or solid, and it is known to be hygroscopic, requiring specific handling and storage conditions to maintain its stability. This includes storage under refrigeration (2-8°C) and in a dry environment, preferably under an inert gas, to prevent degradation. Solubility in common organic solvents such as chloroform, ethyl acetate, and methanol further dictates its utility in various reaction matrices used in organic synthesis.

The primary application of 3-Oxo Citalopram lies in its role as a key precursor in the multi-step synthesis of Citalopram. Its structural framework contains essential chemical moieties that are crucial for building the final Citalopram molecule. Therefore, when pharmaceutical companies engage in pharmaceutical intermediate sourcing, finding reliable suppliers for high purity 3-Oxo Citalopram is a top priority. This ensures the efficiency of the synthesis process and the ultimate quality of the Active Pharmaceutical Ingredient (API).

Researchers looking to buy 3-Oxo Citalopram online often perform searches using specific long tail keywords like “Citalopram synthesis intermediate” or “CAS 372941-54-3 pharmaceutical”. The availability of this compound from trusted pharmaceutical intermediate suppliers, particularly those based in regions like China, facilitates research and large-scale production alike. The consistent availability of high-quality intermediates is critical for maintaining a stable supply chain for essential medications.

In summary, 3-Oxo Citalopram is more than just a chemical compound; it is a vital link in the chain of pharmaceutical innovation and production. A thorough understanding of its chemical properties, synthesis applications, and market availability empowers researchers and manufacturers to optimize their processes and contribute to the availability of critical mental health therapies.
