Description

FORMAMIDINIUM IODIDE CH₃IN₂ 99% FAI CAS 879643-71-7

RESEARCH GRADE MATERIAL

Product Overview
Formamidinium Iodide (CH₃IN₂, FAI, CAS 879643-71-7) is a core formamidinium-based perovskite solar cell precursor with CH₃IN₂ 99% purity FAI, supplied as an off-white solid with a molecular weight of 171.97 g/mol. This high-purity organohalide salt is frequently combined with methylammonium iodide to fabricate high-stability formamidinium-based perovskite thin films with enhanced thermal and moisture resistance compared to pure MAPbI₃ compositions. The material is widely employed in university and research institute laboratories for photovoltaic cell, photodetector, and light-emitting device development. Compatible with mainstream thin-film processing techniques including solution spin-coating and thermal evaporation, the precursor delivers stable optoelectronic output performance with low batch impurity content. 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.

Key Features & Advantages
  • Enhanced Thermal Stability for Formamidinium-Based Perovskites: Formamidinium-based perovskite films exhibit superior thermal stability compared to methylammonium-based compositions, making FAI the preferred precursor for high-performance photovoltaic devices requiring extended operational lifetimes.
  • Ultra-High Purity Exceeding 99%: The formamidinium iodide is refined to >99% purity with low batch impurity content, minimizing extrinsic ionic defects in perovskite thin films and supporting reproducible device performance across various deposition techniques.
  • Versatile Compatibility with Mixed-Cation Formulations: Frequently combined with methylammonium iodide and cesium iodide for triple-cation perovskite compositions, enabling precise bandgap tuning and improved phase stability in high-efficiency photovoltaic research.
  • Room Temperature Storage Convenience: The material is stored at room temperature under light-protected, dry, sealed conditions, simplifying laboratory inventory management without requiring refrigeration or freezing equipment.

APPLICATION SCOPE: Primary formamidinium source for FAPbI₃ and mixed-cation FA-based perovskite light-absorbing layer synthesis in high-efficiency single-junction and tandem solar cells. Essential precursor for mixed-cation mixed-halide perovskite formulations combining FA, MA, and Cs cations. Compatible with one-step spin-coating, two-step sequential deposition, and thermal evaporation deposition protocols. Supports photodetector, perovskite light-emitting diode, and other optoelectronic device research in university and institutional laboratory settings.
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 formamidinium 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: Formamidinium 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 acidic reagents. Exposure to atmospheric moisture will cause deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. When preparing precursor solutions, handle the off-white solid within an inert-atmosphere glovebox (H₂O < 1 ppm, O₂ < 1 ppm). For detailed safety and handling information, consult the Safety Data Sheet prior to use.
