Description

Methyl Isovalerate CAS NO 556-24-1 is a clear, colorless ester with a characteristic fruity, apple-like aroma. This compound is valued as a versatile flavor and fragrance intermediate, prized for its clean, ester-like profile and high volatility. It is essential for manufacturers in the flavor & fragrance, food & beverage, and specialty chemical industries seeking to create or enhance specific fruity notes in their products.

Application

• Flavor & Fragrance (F&F) Industry: A key building block for synthesizing and formulating fruity flavors (e.g., apple, banana) and fragrances in perfumes, cosmetics, and personal care products.
• Food & Beverage Additive: Used as a synthetic flavoring agent to impart or enhance fruity notes in candies, beverages, baked goods, and dairy products.
• Chemical Synthesis: Serves as a valuable intermediate or starting material in organic synthesis for pharmaceuticals, agrochemicals, and other fine chemicals.
• Solvent & Extraction Agent: Employed as a specialty solvent in specific laboratory and industrial processes due to its selective solvency and volatility.
• Aroma Chemical Production: A fundamental component in the production of complex aroma chemicals and essential oil reconstructions.

Quality Control

Our Methyl Isovalerate is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. We offer grades suitable for flavor & fragrance and industrial applications. All products are accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and key physical parameters. Specifications can be tailored to meet specific customer requirements, including compliance with relevant standards such as FCC (Food Chemicals Codex) for food-grade applications.

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 15-25°C.
