METHYLAMMONIUM CYANATE CH₆N₂O 99% CAS 63405-91-4

RESEARCH GRADE MATERIAL

Product Overview

Methylammonium Cyanate (CH₆N₂O, CAS 63405-91-4) is a cyanate anion-modified methylamine-based organic salt perovskite precursor with CH₆N₂O 99% purity, supplied as a white solid powder with a molecular weight of 74.07 g/mol and soluble in perovskite-relevant polar organic solvents including DMF and DMSO. This compound functions as an effective perovskite crystallization modulator, where the cyanate anion participates in perovskite lattice coordination, regulating crystal nucleation and growth kinetics while optimizing thin film grain size. The cyanate group simultaneously passivates grain boundary and surface defects, reducing non-radiative recombination centers and enhancing charge carrier transport efficiency. Suitable for doping modification research in formamidinium/methylammonium composite perovskite solar cells and photodetectors, this precursor is compatible with spin-coating and precursor solution blending thin-film preparation techniques. With low impurity content and stable experimental data reproducibility, the product requires strict light-sensitive hygroscopic glovebox storage to maintain material integrity.

Key Features & Advantages

Cyanate Anion Lattice Coordination for Crystallization Control: The cyanate anion directly participates in perovskite lattice coordination chemistry, providing a fundamentally different crystallization modulation mechanism compared to halide-only or thiocyanate-based additives, enabling independent control of nucleation density and growth rate.
Grain Boundary and Surface Defect Passivation: The cyanate group effectively coordinates with under-coordinated metal sites at grain boundaries and film surfaces, passivating deep-level trap states and reducing non-radiative recombination losses for enhanced charge carrier transport.
Low Molecular Weight for Precise Stoichiometric Control: With a molecular weight of only 74.07 g/mol, the precursor enables fine stoichiometric adjustment with minimal mass perturbation to the primary perovskite precursor solution composition.
Compatible with Mixed-Cation Perovskite Systems: Suitable for doping modification of formamidinium/methylammonium composite perovskite compositions, supporting bandgap engineering and stability optimization in mixed-cation device architectures.

APPLICATION SCOPE: Cyanate-based crystallization modulator for perovskite thin film nucleation and growth optimization. Grain boundary and surface defect passivation agent for reducing non-radiative recombination. Doping modification precursor for formamidinium/methylammonium composite perovskite solar cells. Carrier transport efficiency enhancement additive for perovskite photodetectors. Compatible with spin-coating and precursor solution blending deposition protocols. Supports perovskite solar cell and photodetector 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 methylammonium cyanate 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: Methylammonium cyanate is hygroscopic and light-sensitive. Tighten the container cap immediately after each use to prevent moisture ingress from ambient air. The cyanate group may present irritant properties—wear protective gloves and a mask throughout all experimental procedures; avoid direct skin contact and inhalation of powder. Store in a light-protected, moisture-free environment; do not store together with strong acids or strong oxidizing agents. 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.
