Description

20-(tert-Butoxy)-20-Oxoicosanoic Acid is a high-purity, synthetic long-chain fatty acid derivative featuring a terminal tert-butoxy keto acid moiety. This specific molecular architecture makes it a valuable and versatile chemical intermediate for advanced organic synthesis and pharmaceutical research. It is primarily utilized by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce functionalized hydrophobic chains into target molecules.

Application

• Pharmaceutical Intermediate: Serves as a key building block for the synthesis of novel drug candidates, particularly in modifying pharmacokinetic properties like lipophilicity.
• Lipid Conjugation Chemistry: Used to create lipid-drug conjugates (LDCs) or to functionalize peptides and proteins to enhance membrane permeability or stability.
• Polymer Science: Acts as a monomer or chain modifier in the production of specialized polyesters and other functional polymers.
• Agrochemical Synthesis: Employed in the research and development of new active ingredients, such as herbicides or plant growth regulators, requiring specific fatty acid-based structures.
• Bioconjugation & Probe Development: Useful for attaching reporter groups or other functionalities to biomolecules in diagnostic and research applications.
• Material Science Research: Investigated for creating self-assembled monolayers (SAMs) or surface modifications due to its long alkyl chain and terminal acid group.
