Description

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.

Methylammonium cyanate is hygroscopic and light-sensitive, requiring strict moisture and light protection. Storage under inert atmosphere (N₂ glovebox with H₂O < 1 ppm, O₂ < 1 ppm) is recommended for long-term stability, and it must be kept away from strong acids and oxidizing agents.

  • Moisture Sensitivity: Exposure to atmospheric moisture causes deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry.
  • Light Protection: Light-sensitive material must be stored in light-protective packaging and transferred to a light-protected environment.
  • Infrastructure Requirement: Powder weighing and solution preparation must be performed within a nitrogen-filled inert glovebox with H₂O < 1 ppm and O₂ < 1 ppm.
  • Compatibility Constraint: The compound is soluble in DMF and DMSO and compatible with spin-coating and precursor solution blending techniques.
  • Storage Condition: Store at room temperature in a dry, sealed, light-protected container; do not store together with strong acids or strong oxidizing agents.

Handling of methylammonium cyanate requires immediate transfer to a glovebox after opening to prevent moisture exposure. Proper protective equipment and inert atmosphere are essential for maintaining material integrity.

How does methylammonium cyanate's crystallization modulation mechanism compare to thiocyanate-based additives for perovskite thin films?

Methylammonium cyanate provides a fundamentally different crystallization modulation mechanism via direct cyanate anion lattice coordination, enabling independent control of nucleation density and growth rate compared to halide-only or thiocyanate-based additives. The cyanate group simultaneously passivates grain boundary and surface defects by coordinating with under-coordinated metal sites, reducing non-radiative recombination centers and enhancing charge carrier transport efficiency.

Is methylammonium cyanate compatible with formamidinium-based perovskite formulations?

Yes, methylammonium cyanate is suitable for doping modification of formamidinium/methylammonium composite perovskite compositions, supporting bandgap engineering and stability optimization in mixed-cation device architectures. It is soluble in DMF and DMSO and compatible with spin-coating and precursor solution blending deposition protocols.

What storage conditions are required to prevent degradation of methylammonium cyanate?

Methylammonium cyanate requires strict light-protected, dry, sealed storage at room temperature; for long-term storage, a nitrogen-filled glovebox with H₂O < 1 ppm and O₂ < 1 ppm is recommended. Exposure to atmospheric moisture causes deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. Immediate transfer to a desiccated, light-protected environment after opening is necessary.

Methylammonium cyanate (CH₆N₂O, 99% purity) functions as a perovskite crystallization modulator via cyanate anion lattice coordination and grain boundary defect passivation, but requires glovebox handling to prevent irreversible hydrolysis and stoichiometry degradation from atmospheric moisture.
