Description

(S)-(+)-4-Penten-2-Ol CAS NO 55563-79-6 is a high-purity, chiral intermediate characterized by its terminal alkene functionality and secondary alcohol group. This compound matters as a versatile building block for synthesizing complex, optically active molecules, which are critical in the development of pharmaceuticals and fine chemicals. Industries that require enantioselective synthesis, such as pharmaceutical R&D, agrochemical manufacturing, and advanced material science, are the primary users of this valuable chiral synthon.

Application

• Pharmaceutical Intermediate: A key chiral precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for drugs targeting the central nervous system and anti-infective agents.
• Agrochemical Synthesis: Used in the production of enantiomerically pure pesticides and herbicides, where the specific stereochemistry can enhance efficacy and reduce environmental impact.
• Ligand and Catalyst Development: Serves as a starting material for creating chiral ligands and organocatalysts used in asymmetric synthesis.
• Flavor and Fragrance Industry: Employed in the synthesis of specific, high-value aroma chemicals where the (S)-enantiomer imparts the desired olfactory profile.
• Material Science Research: Acts as a monomer or functionalization agent in the development of novel polymers with tailored optical or mechanical properties.
• Academic and R&D Laboratories: A standard reagent for methodological studies in organic chemistry, including asymmetric hydrogenation and carbon-carbon bond formation reactions.
