3-Methylfuran[2]

Updated: 2026-09-16

Overview

3-Methylfuran is an organic heterocyclic compound belonging to the furan family. It is a colorless to pale yellow liquid with a characteristic aromatic odor. The compound is widely used in the flavor and fragrance industry due to its pleasant smell, which resembles roasted or caramel-like notes. In addition to its role as a flavoring agent, 3-Methylfuran serves as a key intermediate in the synthesis of various pharmaceuticals and agrochemicals. Its chemical structure makes it a versatile building block for more complex molecules.

Physical and Chemical Properties

3-Methylfuran is a volatile liquid with a boiling point of 65-66°C and a melting point of -80°C. It has a density of 0.913 g/cm³ at 20°C, making it lighter than water. The compound is soluble in most organic solvents but only slightly soluble in water. Its molecular structure includes a furan ring with a methyl group attached at the 3-position. This configuration contributes to its reactivity, particularly in electrophilic substitution reactions. The compound is highly flammable and should be handled with care to avoid ignition.

Main Applications

The primary use of 3-Methylfuran is in the flavor and fragrance industry, where it imparts roasted or caramel-like notes to food products and perfumes. It is commonly found in coffee, meat, and baked goods flavorings. Beyond flavors, 3-Methylfuran is a valuable intermediate in the production of pharmaceuticals and agrochemicals. It is used in the synthesis of certain antibiotics, antifungal agents, and pesticides. Its reactivity allows for the creation of more complex molecules with specific biological activities.

Safety and Storage

3-Methylfuran is highly flammable and poses significant fire and explosion hazards. It should be stored in a cool, dry, well-ventilated area away from heat sources and open flames. Proper grounding and bonding are essential to prevent static discharge. Exposure to 3-Methylfuran can cause irritation to the skin, eyes, and respiratory tract. Prolonged or repeated exposure may lead to more severe health effects. Always use personal protective equipment (PPE) such as gloves, goggles, and respirators when handling this compound.

B2B Procurement Guide

When procuring 3-Methylfuran, it is crucial to verify the supplier's credentials and request a Certificate of Analysis (COA) to ensure product purity and quality. Bulk purchases may offer cost advantages, but proper storage and handling must be ensured. Consider the logistics of transportation, especially given the compound's flammability. Reliable suppliers should provide Material Safety Data Sheets (MSDS) and comply with all relevant regulatory requirements. Pricing can vary based on purity and order volume, typically ranging from $50 to $100 per kilogram.
