Chemical properties:

Specification sheet:

Compared with other chemical products of the same type (such as imidazole, benzimidazole, 2-methylimidazole, etc.), it has the following characteristics and advantages:

1. Structural characteristics
• Phenyl ring substituents: A benzene ring is attached to the imidazole ring of 2-phenylimidazole, giving it a larger conjugated system and greater hydrophobicity.
• Electronic effects: The introduction of the benzene ring enhances the electron density of the imidazole ring, improving its nucleophilicity and coordination ability.
2. Solubility
• Organic solvents: 2-phenylimidazole is easily soluble in most organic solvents (such as ethanol, ether, chloroform, acetone), and has better solubility than unsubstituted imidazole.
• Water solubility: 2-phenylimidazole is less soluble in water, but can increase its water solubility by forming salts such as hydrochloride.
3. Reactivity
• Nucleophilicity: Nitrogen atoms on the imidazole ring of 2-phenylimidazole have high nucleophilicity and can react with electrophilic reagents (such as halogenated hydrocarbons, acyl chloride).
• Coordination ability: 2-phenylimidazole is capable of forming stable complexes with metal ions (e.g. Cu² +, Zn² +) and has a stronger coordination ability than unsubstituted imidazole.
4. Thermal stability
• Thermal decomposition temperature: 2-phenylimidazole has a higher thermal decomposition temperature (>200°C) and is thermally more stable than many other imidazole derivatives (e.g. 2-methylimidazole).
• High temperature applications: 2-phenylimidazole is suitable for reactions and material preparation in high temperature environments.
5. Optical properties
• Ultraviolet absorption: 2-phenylimidazole has a characteristic absorption peak in the ultraviolet region (200-300 nm), and the optical performance is better than that of unreplaced imidazole.
• Fluorescence properties: 2-phenylimidazole has certain fluorescence properties and can be used in fluorescent probes and optical materials.

Epoxy resin curing agent

◆ Promote curing of epoxy resin
2-phenylimidazole can effectively promote the curing process of epoxy resin at low temperature and form a stable three-dimensional network structure
◆ Optimize production process
In some specific epoxy formulations, 2-phenylimidazole can be used as a catalyst to accelerate the reaction between the epoxy and the hardener.
◆ Improve the performance of epoxy resin
By using 2-phenylimidazole as a curing agent, epoxy resins can be modified, thereby improving their processability and the properties of the final product.

Specific application field:

● Electronic packaging material

● Anticorrosive paint

● Epoxy composites

Polyurethane curing agent

◆ Accelerated curing reaction
2-phenylimidazole can effectively promote the curing reaction of polyurethane. During the curing process, it acts as a catalyst to accelerate the cross-linking reaction between the polyurethane molecular chains, thus forming a stable three-dimensional network structure. This structure not only enhances the mechanical properties of the polyurethane material, such as tensile strength, tear strength and hardness, but also improves its heat resistance, chemical resistance and wear resistance.

 

 

Specific application field:

● Paints and adhesives

● Foam material

● Eastomer

Fluorochrome

◆ Fluorescence property
2-phenylimidazole has unique fluorescence emission characteristics, which can fluoresce under the excitation of specific wavelengths of light. 

Specific application field:

● Bioimaging
As a fluorescent dye, 2-phenylimidazole can be used for imaging cells or organisms. By labeling them on specific biomolecules or cell structures, the distribution and dynamic changes of these molecules or structures can be clearly observed under fluorescence microscopy.
● Optical sensing
The fluorescence properties of 2-phenylimidazole can also be used to build optical sensors. This sensor is capable of responding to specific physical, chemical or biological stimuli and produces measurable changes in the fluorescence signal.
