Description

(R)-3-Methyl-Pentanoic Acid CAS NO 16958-25-1 is a chiral, branched-chain fatty acid derivative that serves as a valuable building block in asymmetric synthesis. Its enantiopurity makes it a critical intermediate for the production of high-value pharmaceuticals, agrochemicals, and advanced materials. This compound is essential for research and manufacturing in the pharmaceutical, flavor & fragrance, and specialty chemical industries where precise stereochemistry dictates product efficacy and performance.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in developing stereospecific drugs.
• Agrochemical Synthesis: Used in the production of enantiomerically pure herbicides, pesticides, and plant growth regulators.
• Flavor and Fragrance Ingredient: Serves as a precursor for chiral esters and lactones that contribute to complex, natural flavor profiles.
• Ligand and Catalyst Preparation: Employed in the development of chiral ligands for asymmetric catalysis and metal-organic frameworks (MOFs).
• Advanced Material Research: Building block for liquid crystals, polymers, and other functional materials requiring specific optical properties.
• Biochemical Research: Used in metabolic studies and as a standard for analytical method development in chiral separations.
