Description

S-Methyl Isovalerate is an ester derivative of isovaleric acid, valued for its fruity, apple-like aroma and high volatility. This compound serves as a versatile intermediate and flavor/fragrance ingredient, prized for its purity and consistent performance. It is essential for manufacturers in the flavor & fragrance, pharmaceutical, and agrochemical industries seeking reliable, high-quality synthetic building blocks.

Application

• Flavor & Fragrance (F&F) Industry: A key aroma chemical used in the formulation of fruit flavors (e.g., apple, banana) and perfumery for its fresh, sweet top notes.
• Pharmaceutical Intermediates: Employed as a chiral building block or protecting group reagent in the synthesis of active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Acts as a precursor or intermediate in the production of certain pesticides and herbicides.
• Organic Synthesis: Used as an alkylating agent or ester component in various organic reactions, including transesterification.
• Solvent & Carrier: Functions as a solvent for resins and a carrier in specialty chemical applications due to its volatility.
• Research & Development: Serves as a standard or reagent in analytical chemistry and academic research for method development.

Quality Control

Our S-Methyl Isovalerate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC and IR analysis, to ensure it meets high-purity standards suitable for flavor, fragrance, and synthetic applications. A Certificate of Analysis (COA) detailing purity, identity, and specific impurities is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flames. Recommended storage temperature is 2-8°C (refrigerated) or 15-25°C (controlled room temperature) for extended stability, depending on the specific grade and intended use. Due to its highly volatile nature, keep containers tightly sealed when not in use.
