Description

(S)-2,4-Diaminobutanoic Acid Hydrobromide is a high-purity, non-proteinogenic amino acid derivative, specifically the hydrobromide salt of the (S)-enantiomer of 2,4-diaminobutanoic acid. This compound serves as a critical chiral building block and intermediate in advanced organic synthesis, particularly for the development of novel pharmaceuticals and bioactive molecules. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors who require enantiomerically pure intermediates for drug discovery, peptide synthesis, and the creation of specialized chemical libraries.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), especially those targeting neurological and metabolic pathways.
• Peptide Chemistry: Used in the solid-phase and solution-phase synthesis of modified peptides and peptidomimetics, incorporating its unique diamine functionality.
• Biochemical Research: Serves as a precursor or standard in metabolic studies and enzymatic research involving polyamine biosynthesis.
• Asymmetric Synthesis: Employed as a chiral auxiliary or starting material in catalytic asymmetric reactions to induce stereoselectivity.
• Ligand and Catalyst Development: Useful for constructing novel chelating ligands and organocatalysts due to its multiple nitrogen donor atoms.
• Reference Standard: Utilized as a high-purity analytical standard for quality control and method development in analytical laboratories.
