Isovaleraldehyde
Overview
Isovaleraldehyde, also known as 3-Methylbutanal, is an aldehyde with a molecular formula of C5H10O. It is derived from isovaleric acid and is characterized by its strong, fruity odor. The compound is widely utilized in the flavor and fragrance industry due to its apple-like scent. In addition to its sensory applications, isovaleraldehyde serves as a key intermediate in the synthesis of pharmaceuticals and agrochemicals. Its reactivity makes it valuable for producing various derivatives, including alcohols and acids, through oxidation or reduction processes.
Physical and Chemical Properties
Isovaleraldehyde is a colorless to pale yellow liquid with a density of 0.805 g/cm³ at 20°C. It has a boiling point of 92-93°C and a melting point of -51°C. The compound is soluble in organic solvents like alcohol and ether but only slightly soluble in water. Its chemical properties include reactivity typical of aldehydes, such as participation in condensation and oxidation reactions. The compound is flammable and should be handled with care to avoid ignition. Its pungent odor is detectable at low concentrations, making it useful in flavor formulations.
Main Applications
The primary use of isovaleraldehyde is in the flavor and fragrance industry, where it imparts fruity notes to perfumes, food flavorings, and beverages. Its apple-like aroma makes it a popular choice for synthetic flavorings. In the pharmaceutical sector, it acts as an intermediate for the synthesis of active ingredients. Agrochemical manufacturers also utilize isovaleraldehyde in the production of pesticides and herbicides. Its versatility in organic synthesis underscores its importance in industrial chemistry.
Safety and Storage
Isovaleraldehyde is classified as an irritant, posing risks to skin and eyes upon contact. Proper personal protective equipment (PPE), including gloves and goggles, is essential when handling the compound. Adequate ventilation is necessary to prevent inhalation of vapors. Storage should be in a cool, dry place away from ignition sources and incompatible materials such as strong oxidizers. Containers must be tightly sealed to prevent evaporation and contamination. Spill containment measures should be in place to address accidental releases.
B2B Procurement Guide
When procuring isovaleraldehyde, B2B buyers should prioritize suppliers with certifications such as ISO or GMP to ensure quality and consistency. Purity levels (typically 95-99%) should be verified through analytical certificates. Bulk purchases may offer cost advantages, but storage capacity and shelf life must be considered. Regulatory compliance, including REACH or FDA approvals, is critical for specific applications. Buyers should also evaluate logistics, including packaging (drums, IBCs) and transportation safety measures.
