The Chemical Abstracts Service (CAS) registry number, CAS 15761-38-3, uniquely identifies a specific chemical substance. For those in the fields of chemistry and pharmaceuticals, this number is often the first point of reference for a compound, in this case, N-Boc-L-Alanine. Understanding what this number represents and the properties associated with it is crucial for researchers and manufacturers.

N-Boc-L-Alanine, identified by CAS 15761-38-3, is a derivative of the amino acid L-Alanine, featuring the tert-butyloxycarbonyl (Boc) protecting group on its amino terminus. This modification makes it an invaluable tool in organic synthesis, particularly for peptide synthesis. The Boc group provides temporary protection, enabling controlled coupling reactions during the assembly of amino acid chains. Its physical form is typically a white crystalline powder, with a high purity profile often exceeding 98%, which is critical for its applications.

The significance of CAS 15761-38-3 lies in its direct association with a compound used extensively as a pharmaceutical intermediate and as a fundamental chemical synthesis building block. Whether for academic research exploring new molecular entities or for industrial production of peptide-based drugs, knowing the CAS number ensures that you are ordering the correct material with the expected specifications.

When you are ready to buy N-Boc-L-Alanine, referencing its CAS number is the most precise way to communicate your needs. It eliminates ambiguity and assures both buyer and seller that the specific chemical compound with its unique properties and purity standards is being procured.
