Overview and Chemical Properties

1,3-Cyclohexyldimethylammonium diiodide (Aladdin SKU: C494216) is a geminal- or 1,3-disubstituted cyclohexane derivative bearing two dimethylammonium groups, each charge-balanced by an iodide counterion. The molecule belongs to the class of bis-quaternary ammonium salts and carries a net 2+ cationic charge on its organic core.

As a solid ionic compound, it is expected to exhibit moderate-to-good solubility in polar aprotic solvents such as dimethylformamide (DMF) and dimethyl sulfoxide (DMSO), as well as in water and lower alcohols. The iodide counterions render the compound relevant to iodide-rich reaction environments, including halide perovskite fabrication and iodination chemistry.

Note: Specific physicochemical data (melting point, exact solubility values, molecular weight) are not provided in the current product record. Researchers should consult the Certificate of Analysis (CoA) supplied with each lot.

Safety and Handling

As with all quaternary ammonium iodide salts, appropriate precautions should be taken when handling 1,3-Cyclohexyldimethylammonium diiodide:

• Personal Protective Equipment (PPE): Wear nitrile gloves, safety glasses, and a laboratory coat at all times. Use a dust mask or work in a fume hood if powder generation is anticipated.
• Skin and Eye Contact: Avoid direct contact. In case of skin contact, wash thoroughly with soap and water. For eye contact, flush immediately with copious water and seek medical attention.
• Inhalation: Avoid inhalation of dust or aerosols. Work in a well-ventilated area or fume hood.
• Disposal: Dispose of waste material in accordance with local regulations for halide-containing chemical waste.

Review flag: A formal Safety Data Sheet (SDS) specific to this compound should be consulted prior to use. If an SDS is not yet available in the product listing, contact Aladdin Scientific customer service.

Solution Preparation Protocol

The following general protocol is recommended for preparing stock solutions of 1,3-Cyclohexyldimethylammonium diiodide. Adjust volumes and concentrations to suit your specific experimental requirements.

1. Equilibrate to room temperature: Remove the reagent vial from storage and allow it to equilibrate to room temperature (approximately 20–25 °C) before opening, to prevent moisture condensation on the solid.
2. Weigh accurately: Tare a clean, dry vessel (e.g., glass vial or weighing boat). Using an analytical balance, weigh the required amount of compound.
3. Solvent selection: For most applications, polar aprotic solvents (DMF, DMSO) or water are recommended starting points. Verify solvent compatibility with your downstream application before proceeding.
4. Dissolution: Add the weighed solid to approximately 80% of the final target volume of solvent. Stir or vortex until complete dissolution is achieved. If necessary, gentle warming (≤40 °C) may assist dissolution; avoid excessive heat.
5. Adjust to final volume: Transfer the solution to a volumetric flask and make up to the final volume with the chosen solvent. Mix thoroughly.
6. Filter if required: Pass the solution through a 0.22 µm syringe filter if particulate-free solution is required (e.g., for thin-film deposition).
7. Label and store: Label the solution with compound name, concentration, lot number, date of preparation, and preparer's initials. Store according to the conditions specified below.

Note: Verified solubility data are not available in the current product record. Conduct a small-scale trial dissolution before preparing large-volume stocks.

Storage Conditions

Proper storage is essential to maintain the integrity and activity of 1,3-Cyclohexyldimethylammonium diiodide:

• Temperature: Store at room temperature or in a cool environment (2–8 °C if long-term stability is required). Consult the CoA for lot-specific recommendations.
• Light: Protect from light. Iodide salts can undergo photochemical oxidation, generating iodine (I₂) and potentially discoloring or degrading the material.
• Moisture: Store in a tightly sealed container under dry conditions. Hygroscopic behavior is common among ionic salts; exposure to humidity can lead to caking or hydrolytic degradation.
• Atmosphere: Where possible, store under inert gas (nitrogen or argon) if the compound is moisture- or oxygen-sensitive.
• Prepared solutions: Use freshly prepared solutions where possible. If storage of solutions is necessary, keep in sealed containers protected from light and use within a timeframe validated for your application.
