FORMAMIDINIUM CHLORIDE CH₅CLN₂ 99.99% FACL CAS 6313-33-3

RESEARCH GRADE MATERIAL

Product Overview

Formamidinium Chloride (CH₅ClN₂, FACl, CAS 6313-33-3) is a chlorine-based formamidinium perovskite precursor with CH₅ClN₂ 99.99% purity FACl, supplied as a white powder with a molecular weight of 80.52 g/mol and soluble in ethanol. This ultra-high-purity organohalide salt functions as a perovskite lattice modulation precursor, where chloride ions are introduced to regulate the perovskite crystal lattice structure, modulate material bandgap, and simultaneously passivate grain boundary defects in the resulting thin film. The chloride incorporation improves charge carrier transport efficiency by reducing trap-mediated recombination pathways. Primarily employed in formamidinium-based hybrid perovskite thin film preparation, this ultra-high-purity grade with extremely low impurity content is suitable for photovoltaic cell, photodetector, and photocatalytic device research in university and research institute laboratories. Compatible with spin-coating and precursor solution blending thin-film preparation techniques, the product requires strict light-sensitive hygroscopic dry storage to maintain stoichiometric integrity.

Key Features & Advantages

Ultra-High Purity Exceeding 99.99%: The formamidinium chloride is refined to >99.99% purity with extremely low batch impurity content, making it suitable for applications requiring the highest levels of precursor purity where even trace contaminants compromise device performance and experimental reproducibility.
Chloride-Mediated Lattice and Bandgap Modulation: Chloride ion incorporation into formamidinium-based perovskite lattices enables controlled modification of crystal structure parameters and electronic bandgap, providing an additional dimension of compositional engineering for optimized device performance.
Dual Function: Grain Boundary Passivation with Carrier Transport Enhancement: FACl simultaneously passivates grain boundary defects while improving charge carrier transport efficiency, reducing trap-mediated recombination without compromising inter-grain electrical connectivity.
Ethanol Solubility for Processing Flexibility: The compound’s solubility in ethanol provides an alternative solvent pathway for precursor solution formulation, complementing conventional DMF- and DMSO-based processing protocols.

APPLICATION SCOPE: Chlorine source for formamidinium-based mixed-halide perovskite thin film preparation. Lattice structure modulator for FA-based perovskite compositional engineering. Grain boundary passivation additive for reducing trap-mediated recombination in perovskite solar cells. Bandgap tuning precursor through chloride incorporation in mixed-halide formulations. Compatible with spin-coating and precursor solution blending deposition protocols. Supports photovoltaic cell, photodetector, and photocatalytic device 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 formamidinium chloride 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 chloride 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 alkaline reagents. Exposure to atmospheric moisture will cause deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. When preparing precursor solutions, handle the white powder within an inert-atmosphere glovebox (H₂O < 1 ppm, O₂ < 1 ppm). The compound is soluble in ethanol. For detailed safety and handling information, consult the Safety Data Sheet prior to use.
