Description
TCI C2240 2-(2-Chlorophenyl)-4,5-diphenylimidazole is a trisubstituted imidazole compound classified as a heterocyclic building block. Its imidazole core carries two phenyl groups at positions 4 and 5 together with a single 2-chlorophenyl group at position 2, producing a large aromatic molecule with an extended conjugated electron system. This structure is widely known in chemistry as the lophine framework, which has attracted the attention of researchers because of its optical properties. In the laboratory, compounds of this type are used both as synthetic intermediates and as subjects of study in research on photoactive materials and chemical sensors.
The properties that make this compound a preferred choice are the combination of an imidazole core capable of acting as both a hydrogen bond donor and acceptor, and a polyaryl framework that provides structural rigidity along with fluorescence behaviour. The presence of a chlorine atom at the ortho position of the phenyl ring influences the torsion angle between the rings, and this has a clear effect on the emission behaviour of the molecule. The compound is a crystalline solid that remains stable under ordinary storage and dissolves in common organic solvents, making it convenient to handle in spectroscopic measurements.
In Indonesian laboratories, this material fits naturally into university research groups, materials chemistry laboratories, and synthetic organic chemistry work where heterocyclic building blocks are required. The good solubility in common organic solvents means it can be prepared directly for spectroscopic measurement without special dissolution procedures. Pack sizes of 5 g and 25 g give flexibility for work ranging from small exploratory experiments to more extensive study programmes, allowing groups to select a quantity that matches the scale of their planned work.
Laboratory Applications
Synthetic intermediate work: the trisubstituted imidazole core serves as a heterocyclic building block that can be carried forward into further synthetic steps in organic chemistry laboratories.
Photoactive materials research: the lophine framework and its extended conjugated electron system make this compound a recognised subject of study for researchers investigating optical behaviour in aromatic molecules.
Chemical sensor development: the imidazole core can act as both a hydrogen bond donor and acceptor, a property that supports investigations into molecular recognition and sensing behaviour.
Fluorescence and emission studies: the polyaryl framework provides structural rigidity and fluorescence properties, while the ortho chlorine substituent influences inter-ring torsion angles and therefore emission behaviour.
Spectroscopic measurement work: because the compound dissolves in common organic solvents, sample solutions can be prepared straightforwardly for routine spectroscopic characterisation and comparison studies.

Handling and Storage
This compound is a crystalline solid that remains stable under ordinary storage conditions, so it does not require unusual handling arrangements. Keep the material in its original tightly closed container, or transfer it to a clean, dry, well-sealed glass container clearly labelled with the compound name and CAS number. Store in a dry area away from direct sunlight and sources of moisture, and reseal the container promptly after each use to limit exposure to air and humidity. As with any laboratory chemical, handle the solid in a well-ventilated area or fume hood, wear a laboratory coat, safety glasses, and appropriate gloves, and avoid inhalation of dust or direct contact with skin and eyes. Use clean, dry spatulas when weighing to prevent contamination of the stock material, and consult the manufacturer's safety data sheet before beginning work.
