Description

α-Ethyl-2,5-Dimethylbenzhydryl Alcohol CAS NO 56431-19-7 is a substituted benzhydryl alcohol derivative, a versatile chiral intermediate and building block in advanced organic synthesis. Its value lies in its unique sterically hindered structure, which is critical for imparting specific stereochemical and physical properties to target molecules. This compound is essential for research and development chemists in the pharmaceutical and fine chemical industries, particularly for creating novel active pharmaceutical ingredients (APIs), liquid crystals, and specialty polymers.

Application

• Pharmaceutical Intermediate: A key chiral precursor in the synthesis of complex drug molecules, especially those targeting central nervous system (CNS) disorders.
• Liquid Crystal Materials: Serves as a core component in the production of advanced liquid crystal displays (LCDs) due to its rigid, substituted biphenyl-like structure.
• Asymmetric Catalyst Ligand: Used in the development of chiral ligands for metal-catalyzed asymmetric reactions, enhancing enantioselectivity.
• Fine Chemical Synthesis: Employed as a building block for fragrances, agrochemicals, and other high-value specialty chemicals.
• Polymer Modification: Acts as a monomer or chain modifier to introduce steric bulk and improve the thermal stability of engineered polymers.
• Academic & Industrial R&D: A valuable reagent for methodological studies in organic chemistry and material science research.
