Description

2-Pentanol,4-(3-Ethyl-5-Methylphenoxy)-,(2R,4S)-(9Ci) is a high-purity, stereochemically defined chiral compound with the CAS registry number 700370-84-9. This specificity makes it a valuable intermediate for the synthesis of complex molecules where precise stereochemistry is critical for biological activity or material properties. It is primarily sought after by research and development teams in the pharmaceutical and advanced agrochemical sectors for use in process chemistry and novel active ingredient development.

Application

• Pharmaceutical Intermediate: A key chiral building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for candidates targeting central nervous system (CNS) disorders or metabolic diseases.
• Agrochemical Research: Used in the development of novel, stereoselective herbicides, fungicides, or plant growth regulators where the specific enantiomer can enhance efficacy and reduce environmental impact.
• Liquid Crystal & Advanced Material Synthesis: Serves as a precursor for chiral dopants or mesogenic units in the production of advanced liquid crystal displays (LCDs) and other functional organic materials.
• Asymmetric Catalysis Ligand Precursor: The defined stereocenters make it a suitable starting material for synthesizing sophisticated chiral ligands used in asymmetric hydrogenation and other catalytic transformations.
• Fine Chemical & Specialty Intermediates: Employed in custom synthesis and contract manufacturing for producing high-value, low-volume specialty chemicals for diverse industrial applications.
