N-Boc-(3S)-3-Phenyl-3-Aminopropionaldehyde, more commonly known by its CAS number 135865-78-0 and chemical name (S)-Tert-Butyl 3-Oxo-1-Phenylpropylcarbamate, is a highly valued molecule in the realm of pharmaceutical chemistry. Its well-defined stereochemistry and reactive functional groups make it an indispensable building block for constructing complex drug molecules. The primary application driving its demand is its role as a crucial intermediate in the synthesis of Maraviroc, an important antiviral medication used in the treatment of HIV.

The synthesis of such intermediates often involves sophisticated organic chemistry techniques to ensure high yields and enantiomeric purity. Researchers are constantly refining these processes to make them more efficient and cost-effective. The availability of (S)-Tert-Butyl 3-Oxo-1-Phenylpropylcarbamate from reliable manufacturers is a testament to the advancements in synthetic methodologies. Its unique structure allows for targeted modifications, leading to the development of other therapeutic agents, particularly those that interact with cellular receptors like CCR5.

Beyond its established role in Maraviroc production, this intermediate is also instrumental in research exploring novel treatments for various conditions. The pursuit of new drug candidates often requires chemists to synthesize libraries of related compounds, and intermediates like CAS 135865-78-0 provide an excellent starting point for such explorations. For companies looking to purchase this chemical, it is vital to partner with suppliers who can guarantee consistent quality and provide the necessary documentation, such as Certificates of Analysis (CoA) and Material Safety Data Sheets (MSDS). This ensures compliance and supports the rigorous demands of pharmaceutical manufacturing and research.
