Description

[R,(-)]-2-Ethylhexanoic Acid CAS NO 56006-48-5 is the single enantiomer of 2-ethylhexanoic acid, a chiral carboxylic acid of significant industrial importance. This optically pure form is critical for applications where stereochemistry directly influences performance, such as in the synthesis of chiral catalysts, pharmaceuticals, and advanced materials. It is primarily sought by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors who require high-purity chiral building blocks.

Application

• Chiral Intermediate in Pharmaceutical Synthesis: Used as a key building block for active pharmaceutical ingredients (APIs) where the (R)-enantiomer imparts specific biological activity.
• Catalyst and Ligand Preparation: Serves as a precursor for synthesizing chiral metal-organic catalysts and ligands used in asymmetric synthesis.
• Agrochemical Production: Employed in the manufacture of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Polymer Additives: Used to produce chiral stabilizers, plasticizers, and other performance additives for advanced polymers.
• Flavor and Fragrance Industry: Acts as an intermediate for creating specific stereoisomers of flavor and aroma compounds.
• Analytical Standards and Research: Provides a high-purity reference standard for chromatographic analysis and academic research in stereochemistry.

Quality Control

Our [R,(-)]-2-Ethylhexanoic Acid is produced under strict quality management systems. Each batch is characterized for identity, purity, and enantiomeric excess (e.e.) using advanced analytical techniques including chiral HPLC, GC, and NMR. We provide comprehensive Certificates of Analysis (COA) detailing all specifications. The product meets high-purity standards suitable for pharmaceutical and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). As a strong acid/organic solvent that is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation to maintain optical purity and prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
