Description

(S)-n-Boc-2-Aminobutylamine CAS NO 1336411-15-4 is a high-purity, single-enantiomer chiral building block essential for advanced organic synthesis. This compound matters because it provides a protected primary amine and a secondary amine handle, enabling the controlled, stereoselective construction of complex molecules. Pharmaceutical researchers and fine chemical manufacturers need it for developing active pharmaceutical ingredients (APIs), peptide mimetics, and other biologically active compounds where chirality is critical.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the research and development of novel therapeutic agents, including protease inhibitors and receptor modulators.
• Peptidomimetic Chemistry: Used to introduce chiral, non-natural amino acid residues into peptide backbones to enhance stability and bioavailability.
• Asymmetric Synthesis: Serves as a versatile precursor for catalysts and ligands used in enantioselective transformations.
• Bioconjugation & Linker Chemistry: The differentially protected amine groups allow for selective functionalization, useful in creating antibody-drug conjugates (ADCs) and diagnostic probes.
• Agrochemical Research: Employed in the synthesis of chiral active ingredients for crop protection products.
• Material Science: Building block for chiral polymers and advanced functional materials with specific optical properties.
