2-Methylimidazole CAS#693-98-1

H2: Product Overview

2-Methylimidazole (abbreviated as 2-MI), molecular formula C₄H₆N₂, EC number 211-765-7, is a heterocyclic aromatic compound. It appears as white or pale yellow crystalline solid at room temperature. The imidazole ring structure endows it with unique alkaline activity and thermal latency. It is a high-value fine chemical intermediate and latent curing accelerator widely used in epoxy, pharmaceutical, material synthesis and biochemical research fields.

H2: Product Application

H3: Biochemical & Synthetic Intermediate

2-Methylimidazole is a monomethylated imidazole that can be used as a building block in the preparation of a wide range of biologically active compounds. 2-Methylimidazole as well as other imidazoles can be used as catalyst for refolding of enhanced coloured fluorescent protein. 2-Methylimidazole has been identified as a byproduct of fermentation and is detected in foods and mainstream and sidestream tobacco smoke. It also serves as a ligand and structural regulator for synthesis of MOF materials, zeolitic imidazolate frameworks and functional nanomaterials.

H3: Epoxy Resin Curing & Acceleration

It acts as latent curing agent and curing accelerator for epoxy resin systems. It is commonly matched with dicyandiamide to extend the room-temperature pot life while achieving fast crosslinking under heating. It is widely used for PCB laminates, electronic potting compounds, solder mask, structural adhesives and composite materials. Cured epoxy parts show high thermal deformation temperature, good mechanical strength and stable insulation performance.

H3: Coatings, Adhesives & Composite Materials

Applied in one-component epoxy powder coatings, structural adhesives and carbon fiber composites. It helps to improve bonding strength, chemical resistance and heat resistance of coating films. It is also used in rubber modification and thermosetting resin formulation.

H3: Pharmaceutical & Agrochemical Intermediates

It is a key raw material for synthesizing imidazole-series drugs, bactericides and plant growth regulators. It participates in the construction of heterocyclic skeletons for multiple bioactive molecules.

H2: FAQ

H3: Q1: What is the difference between 2-Methylimidazole and 2-Ethyl-4-methylimidazole?

A1: 2-Methylimidazole has higher reactivity and higher curing temperature, providing higher Tg for cured epoxy. 2-Ethyl-4-methylimidazole features lower melting point and milder curing condition. Customers can select grades according to their curing process requirement.

H3: Q2: Can I get free samples for lab test?

A2: Small lab samples are available for formula testing. Sample freight cost can be negotiated separately.

H3: Q3: Will 2-Methylimidazole absorb moisture?

A3: It is hygroscopic crystalline solid. Keep packages tightly sealed. Long-term exposure to humid air may cause caking, which will affect dispersion performance in resin.

H3: Q4: What trade terms can you support?

A4: EXW, FCA, FOB, CIF, DAP and other international trade terms are supported based on your logistics arrangement.
