Overview
2-Methylfuran (2-MF) is a five-membered heterocyclic compound derived from furan, with a methyl group at the 2-position. It is widely used as a building block in organic synthesis and as a flavoring agent due to its sweet, woody aroma. Industrially, it is produced via catalytic hydrogenation of furfural or through biomass-derived processes. Its reactivity and solubility make it valuable in pharmaceuticals, agrochemicals, and specialty chemicals.
Physical and Chemical Properties
2-Methylfuran is a volatile liquid with a boiling point of 63–65°C and a distinct aromatic odor. Its low density (0.913 g/cm³) and solubility in organic solvents facilitate its use in reactions. The compound is highly flammable (flash point: -26°C) and forms explosive mixtures with air. It undergoes electrophilic substitution reactions typical of furans, such as nitration and sulfonation, but is sensitive to strong oxidizers.
Main Applications
In pharmaceuticals, 2-MF serves as an intermediate for antihistamines and antiseptics. Agrochemical manufacturers use it to synthesize pesticides and herbicides. Its flavoring properties are exploited in food additives, particularly for coffee and chocolate flavors. Additionally, it is a solvent for resins and dyes, and research explores its potential as a biofuel component.
Safety and Storage
Due to its flammability, 2-Methylfuran requires storage in tightly sealed containers under inert gas (e.g., nitrogen) and away from heat or sparks. Grounding and anti-static equipment are mandatory during transfer. Exposure risks include respiratory irritation and CNS depression. OSHA recommends airborne exposure limits (PEL) of 5 ppm. Spills should be contained with non-combustible absorbents.
B2B Procurement Guide
Buyers should prioritize suppliers with analytical certificates (e.g., GC-MS reports) confirming purity (≥98%). Packaging options range from 1 kg bottles to 200 kg drums, with hazmat shipping compliance (UN 1993). For large-scale procurement, negotiate contracts with batch consistency guarantees. Spot prices fluctuate with furfural feedstock availability, so monitor market trends.
