Description

Pentanoic Acid, 3-[[(1,1-Dimethylethoxy)Carbonyl]Amino]-, (3S)- (9Ci) is a chiral, N-Boc-protected amino acid derivative that serves as a critical building block in organic synthesis. This high-purity intermediate is essential for ensuring stereochemical integrity and yield in complex multi-step reactions. It is primarily utilized by pharmaceutical R&D and production teams for the synthesis of active pharmaceutical ingredients (APIs), peptides, and other fine chemicals where precise molecular architecture is required.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the research and commercial-scale production of active pharmaceutical ingredients (APIs) and drug candidates.
• Peptide Synthesis: Used as a protected amino acid building block in solid-phase and solution-phase peptide synthesis.
• Asymmetric Synthesis: Employed in the construction of complex organic molecules requiring the introduction of a specific stereocenter.
• Bioconjugation & Linker Chemistry: Utilized in the development of antibody-drug conjugates (ADCs) and other bioconjugates where a carboxylic acid handle is needed.
• Chemical Research & Development: Serves as a versatile starting material or intermediate in academic and industrial research for novel compound libraries.
• Agrochemical Synthesis: Potential intermediate in the development of chiral agrochemicals and pesticides.
