Product Overview
|
| Methylammonium Iodide (CH₃NH₃I, MAI, CAS 14965-49-2) is a core iodine-based perovskite solar cell precursor with CH₃NH₃I 99% purity MAI, supplied as a white crystalline solid with a molecular weight of 159.5 g/mol. This high-purity organohalide salt serves as the fundamental precursor for MAPbI₃, FAPbI₃, and mixed-cation cesium-containing composite perovskite solution formulations. The material exhibits excellent solubility in water, N,N-dimethylformamide, and dimethyl sulfoxide, with additional solubility in methanol and isopropanol, enabling versatile precursor preparation across multiple deposition protocols. Widely utilized in laboratory perovskite thin film preparation, optoelectronic device fabrication, and photodetector research, this high-purity precursor is compatible with spin-coating, vacuum thermal evaporation, and solution-based synthetic techniques. Due to its strongly hygroscopic nature, the product requires strict light-sensitive hygroscopic dry storage—sealed under inert atmosphere, protected from light, and maintained at room temperature—to preserve stoichiometric integrity prior to precursor solution preparation. |

Key Features & Advantages
|
- Fundamental Precursor for Hybrid Perovskite Formulations: MAI serves as the core iodine source for MAPbI₃, mixed-cation FA/MA, and cesium-containing composite perovskite solutions, making it the essential starting material for virtually all hybrid perovskite thin film research.
- Broad Solvent Compatibility for Versatile Processing: Excellent solubility in water, N,N-dimethylformamide, and dimethyl sulfoxide, with additional solubility in methanol and isopropanol, enables flexible precursor solution formulation across spin-coating, vacuum evaporation, and solution-based synthetic routes.
- Defined Molecular Weight for Precise Stoichiometry: With a molecular weight of 159.5 g/mol, the precursor supports accurate molar calculations for MAPbI₃ and mixed-cation mixed-halide perovskite formulations, essential for bandgap engineering and compositional optimization studies.
- Ultra-High Purity Exceeding 99%: Refined to >99% purity with low batch impurity content, the precursor minimizes extrinsic ionic defects in perovskite thin films and supports reproducible device performance across multiple deposition techniques.

APPLICATION SCOPE: Primary iodine source for MAPbI₃ and mixed-cation FA/MA/Cs perovskite light-absorbing layer synthesis. Essential precursor for FAPbI₃ and FA/Cs composite perovskite solution formulations. Compatible with one-step spin-coating, two-step sequential deposition, vacuum thermal evaporation, and solution-based synthetic protocols. Supports perovskite thin film preparation, optoelectronic device fabrication, and photodetector research in university and research institute laboratories.
PACKAGING: This listing is for the 10 g specification. Other packaging weights are available upon custom request. Each package is sealed under inert atmosphere within light-protective packaging to prevent photodegradation and moisture ingress. The strongly hygroscopic nature of methylammonium iodide necessitates immediate transfer to a desiccated, light-protected storage environment upon receipt. For bulk quantities or custom packaging specifications, please contact us via email.
IMPORTANT NOTICE: Methylammonium iodide is strongly hygroscopic and light-sensitive. Tighten the container cap immediately after each use to prevent moisture ingress from ambient air. Wear protective gloves throughout all experimental procedures to avoid direct skin contact. Store in a light-protected, moisture-free environment; do not store together with strong oxidizing agents or strong acids. Exposure to atmospheric moisture will cause deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. When preparing precursor solutions, handle the white crystalline solid within an inert-atmosphere glovebox (H₂O < 1 ppm, O₂ < 1 ppm). The compound is freely soluble in water, DMF, and DMSO, and soluble in methanol and isopropanol. For detailed safety and handling information, consult the Safety Data Sheet prior to use.
