Description

(S)-2-Methylbutyl Acetate CAS NO 6493-92-1 is a high-purity, chiral ester valued for its distinct organoleptic properties and utility as a specialty solvent and intermediate. Its primary commercial significance lies in its role as a key chiral building block for asymmetric synthesis and as a source of specific flavor and fragrance notes. This product is essential for manufacturers in the flavor & fragrance, pharmaceutical, and fine chemical industries seeking high-quality, optically active ingredients.

Application

• Flavor & Fragrance Industry: Used as a chiral component in the synthesis of complex flavor and fragrance compounds, contributing fruity, banana-like notes.
• Pharmaceutical Intermediates: Serves as a valuable chiral synthon in the asymmetric synthesis of active pharmaceutical ingredients (APIs) and other bioactive molecules.
• Fine Chemical Synthesis: Acts as a specialized solvent and reagent in stereoselective reactions and catalytic processes requiring specific enantiomeric control.
• Research & Development: Employed in academic and industrial R&D for method development in organic synthesis and chiral analysis.
• Specialty Solvent: Functions as a high-purity, low-residue solvent for sensitive applications in electronics or analytical chemistry.

Quality Control

Our (S)-2-Methylbutyl Acetate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high enantiomeric purity. Each lot is subjected to comprehensive analytical testing, including chiral HPLC or GC analysis, to verify identity, purity, and optical rotation. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality attributes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids, bases, and oxidizing agents. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability, though short-term storage at 15-25°C is acceptable.
