Description

T-Butyl Ester CAS NO 1353979-28-8 is a high-purity synthetic intermediate belonging to the class of tert-butyl esters, valued for its role as a versatile building block in advanced organic synthesis. Its primary commercial significance lies in providing a protected carboxylic acid group that can be selectively deprotected under mild acidic conditions, enabling complex multi-step syntheses. This compound is essential for research and development chemists and production units in the pharmaceutical, agrochemical, and specialty chemical industries who require reliable, high-quality intermediates for API and fine chemical manufacturing.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly where acid-sensitive protecting groups are required.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators.
• Peptide Chemistry: Serves as a protecting group for carboxylic acid functionalities during solid-phase and solution-phase peptide synthesis.
• Material Science Research: Intermediate in the development of novel polymers, liquid crystals, and organic electronic materials.
• Cross-Coupling Reactions: Potential substrate in palladium-catalyzed reactions like Suzuki or Heck couplings for constructing complex molecular architectures.
• Fine Chemical Production: Employed in the manufacture of flavors, fragrances, and other high-value specialty chemicals.
