Description

N-BUTYLAMMONIUM IODIDE C₄H₁₂IN 99% BAI CAS 36945-08-1

RESEARCH GRADE MATERIAL

Product Overview
n-Butylammonium Iodide (C₄H₁₂IN, BAI, CAS 36945-08-1) is a short-alkyl-chain organic iodide salt with C₄H₁₂IN 99% purity BAI, supplied as a white powder with a molecular weight of 201.05 g/mol. This compound functions as a 2D quasi-2D perovskite spacer precursor, where the four-carbon butyl chain modulates interlayer spacing in layered perovskite structures while simultaneously passivating surface and grain boundary defects. The butylammonium cation provides a hydrophobic barrier that blocks moisture ingress, significantly enhancing the environmental stability of perovskite optoelectronic devices. As the iodide analog of BABr, this precursor enables halide composition flexibility in 2D perovskite systems. The material is widely utilized in university and research institute laboratories for photovoltaic cell, photodetector, and light-emitting diode experimental research. Compatible with spin-coating and solution blending thin-film preparation techniques, this high-purity precursor requires strict light-sensitive hygroscopic dry storage to maintain material integrity.

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 hygroscopic nature of n-butylammonium 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: n-Butylammonium iodide is 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 white powder 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.

How does the intermediate butyl chain length in n-butylammonium iodide balance moisture resistance and charge transport in 2D perovskite devices?

The four-carbon butyl chain provides an intermediate steric barrier that enables fine-tuning of interlayer spacing and controlled dimensionality engineering, while simultaneously forming a hydrophobic protective layer at grain boundaries to block moisture ingress. This trade-off allows researchers to balance enhanced environmental stability from moisture blocking against the increased interlayer spacing that can affect charge transport in quasi-2D perovskite systems.

Can n-butylammonium iodide be used interchangeably with BABr to independently tune halide composition in 2D perovskite systems?

Yes, as the iodide analog of BABr, n-butylammonium iodide enables independent control of both the organic spacer cation and halide composition in 2D perovskite systems. This provides an additional degree of freedom for bandgap and stability engineering, allowing researchers to adjust the halide environment without altering the butylammonium spacer structure. The precursor is compatible with spin-coating and solution blending deposition protocols.

What storage and handling infrastructure is required to prevent degradation of n-butylammonium iodide?

n-Butylammonium iodide is hygroscopic and light-sensitive, requiring storage in a light-protected, dry, sealed container at room temperature. For handling, the powder must be transferred within an inert-atmosphere glovebox with H₂O below 1 ppm and O₂ below 1 ppm to prevent deliquescence and hydrolysis. The container cap must be tightened immediately after each use, and the material should not be stored together with strong oxidizing agents or acidic reagents.

This n-Butylammonium Iodide (BAI) provides controlled dimensionality engineering and moisture barrier properties for 2D perovskite research, but demands strict inert-atmosphere handling and light-protected storage to prevent irreversible hydrolysis.
