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.

Key Features & Advantages

Intermediate Chain Length for Controlled Dimensionality: The four-carbon butyl chain provides an intermediate steric barrier between short-chain and long-chain ammonium cations, enabling fine-tuning of interlayer spacing and controlled dimensionality engineering in 2D and quasi-2D perovskite systems.
Effective Moisture Barrier with Grain Boundary Passivation: The butylammonium cation forms a hydrophobic protective layer at perovskite film surfaces and grain boundaries, simultaneously blocking moisture ingress and passivating defect states for enhanced environmental stability.
Iodide Analog for Halide Composition Flexibility: As the iodide counterpart to BABr, this precursor enables independent control of both the organic spacer cation and halide composition in 2D perovskite systems, providing an additional degree of freedom for bandgap and stability engineering.
Ultra-High Purity Exceeding 99%: Refined to >99% purity with low batch impurity content, the precursor minimizes extrinsic defects in quasi-2D perovskite thin films and supports reproducible device performance across experimental batches.

APPLICATION SCOPE: Organic spacer cation for 2D and quasi-2D Ruddlesden-Popper phase perovskite synthesis. Interlayer spacing modulator for tuning optoelectronic properties in layered perovskite structures. Surface and grain boundary passivation agent for mixed-dimensional perovskite thin films. Moisture barrier precursor for environmentally stable perovskite optoelectronic devices. Compatible with spin-coating and solution blending deposition protocols. Supports photovoltaic cell, photodetector, and light-emitting diode 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 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.
