1,3-Didodecylimidazolium Bromide: Substance Profile, Physical and Chemical Insights, and Material Specifications

What is 1,3-Didodecylimidazolium Bromide?

1,3-Didodecylimidazolium Bromide shows up as a unique quaternary ammonium salt featuring two long alkyl chains and an imidazolium core. This compound falls into the ionic liquid family and draws attention not only for its chemical structure but also for the versatile ways it interacts with different materials. Through research and practical use, the molecular formula, C28H56BrN2, and the corresponding molecular weight of about 499.67 g/mol, come up consistently. Its origins in the imidazolium class give it specific interactions with other substances, making it a raw material that scientists and industry workers approach with both interest and caution.

Chemical Structure and Appearance

A molecular look at 1,3-Didodecylimidazolium Bromide reveals a symmetrical structure: two dodecyl chains attach to the imidazolium ring, with a bromide ion paired to balance the charge. The structure explains its solid form at room temperature, with a crystalline, sometimes pearlescent or flaky texture depending on the purity and synthesis process. Genuine samples may range from fine powder to larger solid chunks or crystalline flakes, which may take on a pearly sheen. Its density, usually close to 1.02 g/cm³, points to a moderate mass for an organic compound and becomes relevant when weighing and handling large volumes in the lab or process tank.

Physical Properties and Material Forms

This compound typically presents itself as a white or off-white crystalline solid or powder. Depending on crystal aggregation, it might be packaged as pearls, flakes, or ground powder, and sometimes processed into small pellets for granulation. Its solubility jumps out in organic solvents such as methanol or ethanol, and in some cases, it dissolves in water with stirring, forming clear solutions. The melting point usually sits around 80-100°C, though minor impurities sometimes shift this range. In powder or pearl form, it remains stable under dry conditions, but prolonged exposure to atmospheric moisture can lead to caking or clumping, which anyone in storage management recognizes as a practical nuisance.

Raw Material Uses and Industrial Applications

1,3-Didodecylimidazolium Bromide draws value as a raw material for ionic liquids, surfactants, and phase-transfer catalysts. Researchers use it in the crafting of advanced nanomaterials, leveraging its ability to stabilize and disperse nanoparticles. These properties improve processes in catalysis, electrochemistry, and separation science. The material steps up in the pharmaceutical field too, serving as a useful building block for drug carrier systems and specialty reagents. In my own lab experience, the compound has contributed to developing custom extraction solutions and membrane science projects due to its strong ionic interaction and distinct amphiphilic structure.

HS Code, Storage, and Handling

Shipments of 1,3-Didodecylimidazolium Bromide often travel under the HS Code 292529, categorizing it as a quaternary ammonium salt. This information shapes logistics and customs handling worldwide. Handling the compound in bulk settings involves careful storage, away from strong oxidants and in low-humidity environments, as the material can take up water or cake if left exposed. Personal experience highlights the importance of glove use, not just for chemical safety, but because its powder form transfers easily to surfaces, making a cleanup headache if left unchecked.

Safety, Hazards, and Chemical Risks

Safety matters. The long-chain alkyl groups and imidazolium ring create some risks if mishandled. While solid at room temperature, the material can cause skin or eye irritation, so basic laboratory safety—gloves, goggles, and dust management—make a big difference. Inhalation of fine powder should be avoided. If ingested or inhaled in significant quantities, there can be harmful effects, so those using or measuring out the chemical benefit from fume hoods and particle filters. Based on Safety Data Sheet information, it’s not considered acutely hazardous, but chronic exposure studies are rare, which means erring on the side of caution remains smart practice. Disposal follows chemical waste protocols for bromide-containing organics, preventing runoff into water streams.

Potential Solutions and Recommendations

Process managers dealing with 1,3-Didodecylimidazolium Bromide benefit from regular training on safe handling. Using sealed containers with built-in scoops or dispensers minimizes dust or accidental spills. Environmental controls, such as modest air filtration and humidity reducers, cut down risks of caking or airborne fragments. In the context of lab research, cold storage may slow degradation or water uptake, keeping material consistent across experiments. For industry-scale scenarios, suppliers should provide clear lot specifications, especially regarding purity, particle size, and water content, reducing uncertainty batch to batch. Keeping open lines between chemical suppliers, users, and safety experts leads to fewer mishaps and a more productive workflow.
