Description

Methyl 5-Methylhexanoate is a branched-chain fatty acid methyl ester with a fruity, apple-like aroma. This compound serves as a versatile intermediate and flavor/fragrance component in high-value chemical synthesis. It is particularly relevant for manufacturers in the flavors and fragrances, pharmaceutical intermediates, and specialty chemical sectors seeking reliable, high-purity raw materials.

Application

• Flavor and Fragrance (F&F) Industry: Used as a key aroma chemical and building block for synthesizing complex esters with fruity, green, or apple-like notes.
• Pharmaceutical Intermediates: Acts as a chiral synthon or precursor in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Specialty Solvents and Plasticizers: Employed as a specialty solvent for resins or as a component in high-performance plasticizer formulations.
• Agrochemical Synthesis: Serves as an intermediate in the production of certain pesticides and herbicides.
• Polymer Modification: Can be used as a monomer or co-monomer in the production of specialized polymers and coatings.
• Research and Development: Utilized in organic synthesis and chemical research as a standard or reagent.

Quality Control

Our Methyl 5-Methylhexanoate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets exacting specifications. Certificates of Analysis (COA) detailing all test results are provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is 2-25°C.
