Description

2-Methylhexanoic Acid CAS NO 4536-23-6 is a branched-chain fatty acid valued for its role as a versatile chemical intermediate and flavor/fragrance component. Its unique structure provides specific organoleptic properties and reactivity, making it a critical raw material for high-value synthesis. This product is essential for manufacturers in the flavors & fragrances, pharmaceutical intermediates, and specialty polymer industries seeking consistent quality and reliable supply.

Application

• Flavor and Fragrance Ingredient: Used as a building block for esters and other compounds that impart fruity, cheesy, or waxy notes in food flavors and perfumery.
• Pharmaceutical Intermediate: Serves as a key chiral synthon in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Polymer and Resin Modifier: Acts as a co-monomer or chain terminator to modify the properties of polyesters, alkyd resins, and other polymers.
• Lubricant and Grease Additive: Employed in the production of synthetic esters for high-performance lubricants and metalworking fluids.
• Corrosion Inhibitor Precursor: Used to manufacture derivatives that function as effective corrosion inhibitors in industrial fluids.
• Solvent and Extractant: Finds application in specialty solvent formulations and as an extractant in separation processes.

Quality Control

Our 2-Methylhexanoic Acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, identification, and impurity profile determination, to ensure it meets exacting specifications. A Certificate of Analysis (COA) documenting purity, physical properties, and conformance is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its nature as a strong acid/organic solvent and being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Recommended storage temperature: 15-25°C.
