DIMETHYLAMMONIUM IODIDE C₂H₈IN 99% DMAI CAS 51066-74-1

RESEARCH GRADE MATERIAL

Product Overview

Dimethylammonium Iodide (C₂H₈IN, DMAI, CAS 51066-74-1) is a small-molecule alkyl iodide salt perovskite precursor with C₂H₈IN 99% purity DMAI, supplied as a white solid powder with a molecular weight of 173.99 g/mol and freely soluble in polar solvents including DMF, DMSO, and methanol. This compound functions as an effective perovskite lattice distortion modulator, where the compact dimethylammonium cation is commonly employed for doping modification of three-dimensional perovskites and the preparation of low-dimensional and two-dimensional perovskite materials. The secondary ammonium cation regulates perovskite lattice distortion, optimizes grain size, passivates iodine vacancy defects, and reduces non-radiative recombination losses, thereby enhancing charge carrier mobility and device thermal stability. Compatible with perovskite solar cell, photodetector, and light-emitting diode research applications, this precursor supports spin-coating and precursor co-blending preparation techniques. With stable batch-to-batch purity and low impurity content, the product requires strict light-sensitive hygroscopic glovebox storage to maintain material integrity.

Key Features & Advantages

Compact Secondary Ammonium for Lattice Distortion Engineering: The small dimethylammonium cation introduces controlled lattice distortion in 3D perovskite structures, providing a steric tuning parameter distinct from monovalent primary ammonium cations for modulating crystal symmetry and optoelectronic properties.
Iodine Vacancy Passivation via Secondary Ammonium Chemistry: The dimethylammonium cation effectively stabilizes the local chemical environment around iodine sites, passivating halide vacancy defects that are primary contributors to non-radiative recombination losses in perovskite thin films.
Versatile Application from 3D Doping to Low-Dimensional Perovskites: DMAI serves both as a doping modifier for three-dimensional perovskite compositions and as a precursor for low-dimensional and 2D perovskite material synthesis, providing broad experimental utility across multiple perovskite research domains.
Excellent Polar Solvent Solubility for Processing Flexibility: Freely soluble in DMF, DMSO, methanol, and other polar solvents, the precursor integrates seamlessly into standard perovskite deposition workflows without requiring specialized solvent systems.

APPLICATION SCOPE: Doping modifier for three-dimensional perovskite lattice distortion engineering and grain size optimization. Precursor for low-dimensional and two-dimensional perovskite material synthesis. Iodine vacancy passivation agent for reducing non-radiative recombination in perovskite thin films. Carrier mobility and thermal stability enhancement additive for perovskite solar cells. Compatible with spin-coating and precursor co-blending deposition protocols. Supports perovskite solar cell, photodetector, and light-emitting diode research in university and research institute laboratories.

PACKAGING: This listing is for the 5 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 dimethylammonium iodide necessitates immediate transfer to a desiccated, light-protected storage environment—preferably a nitrogen-filled glovebox for long-term storage. For bulk quantities or custom packaging specifications, please contact us via email.

IMPORTANT NOTICE: Dimethylammonium 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; avoid direct skin contact. Store in a light-protected, moisture-free environment; do not store together with strong oxidizing agents or acidic reagents. Prioritize powder weighing and solution preparation within a nitrogen-filled inert glovebox (H₂O < 1 ppm, O₂ < 1 ppm). For long-term storage, inert-atmosphere glovebox conditions are recommended. Exposure to atmospheric moisture will cause deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. For detailed safety and handling information, consult the Safety Data Sheet prior to use.
