Overview
5-Methyl-3-heptanone, also known as methyl amyl ketone (MAK), is an organic compound belonging to the ketone family. It is commonly used as a solvent and intermediate in chemical synthesis. The compound is characterized by its mild odor and volatility, making it suitable for applications in fragrances and industrial processes. Its molecular structure includes a ketone functional group attached to a seven-carbon chain with a methyl substituent at the fifth position. This configuration influences its physical and chemical properties, such as solubility and boiling point.
Physical and Chemical Properties
5-Methyl-3-heptanone is a colorless to pale yellow liquid with a density of approximately 0.81-0.82 g/cm³. It has a boiling point of 150-152 °C and is soluble in organic solvents like alcohol and ether, though only slightly soluble in water. The compound is flammable and should be handled with care to avoid ignition sources. Its key properties include volatility and a mild odor, which make it useful in applications where evaporation and scent are factors. The molecular weight of 128.21 g/mol and its structural features contribute to its reactivity in chemical reactions.
Main Applications
5-Methyl-3-heptanone is primarily used in the fragrance industry due to its mild, pleasant odor. It serves as a solvent in perfumes and flavorings. Additionally, it is employed as an intermediate in organic synthesis, particularly in the production of other ketones and esters. In industrial settings, it functions as a solvent for resins, coatings, and adhesives. Its volatility makes it suitable for applications requiring fast evaporation rates. The compound is also explored in research for potential uses in pharmaceuticals and agrochemicals.
Safety and Storage
As a flammable liquid, 5-methyl-3-heptanone requires careful handling to prevent fire hazards. It should be stored in a cool, dry, well-ventilated area away from heat sources and open flames. Proper personal protective equipment (PPE), such as gloves and goggles, is recommended when handling the compound. Exposure to the skin or eyes may cause irritation, so immediate washing with water is advised. Inhalation of vapors should be avoided, and adequate ventilation is necessary in workspaces. Spills should be contained and cleaned up promptly using appropriate absorbent materials.
B2B Procurement Guide
When procuring 5-methyl-3-heptanone, B2B buyers should verify the CAS number (541-85-5) to ensure product authenticity. Purity levels, typically ranging from 95% to 99%, should be confirmed based on intended use. Supplier certifications, such as ISO or GMP, can indicate reliable quality. Prices vary depending on quantity and supplier, with a reference range of approximately $50-$100 per kg. Bulk purchases may offer cost savings. Buyers should also consider logistics, such as shipping conditions and storage requirements, to maintain product integrity during transit.
