4-METHOXY-PHENETHYLAMMONIUM BROMIDE C₉H₁₄BRNO 99% 4MEO-PEABR

RESEARCH GRADE MATERIAL

Product Overview

4-Methoxy-Phenethylammonium Bromide (C₉H₁₄BrNO, 4MeO-PEABr) is a modified phenethyl-based organic bromide salt with C₉H₁₄BrNO 99% purity 4MeO-PEABr, supplied as a white solid with a molecular weight of 232.12 g/mol. This compound functions as an advanced 2D perovskite dipole modulator, where the methoxy (-OCH₃) substituent on the aromatic ring introduces an electron-donating group that modulates molecular dipole interactions within the perovskite lattice. This dipole engineering approach optimizes perovskite thin film crystallization quality, passivates grain boundary and surface defects, and enhances both the stability and power conversion efficiency of perovskite optoelectronic devices. The material is utilized in university and research institute laboratories for two-dimensional perovskite solar cell, photodetector, and light-emitting device 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

Methoxy-Functionalized Dipole Engineering: The electron-donating methoxy substituent on the aromatic ring modulates molecular dipole interactions within the perovskite lattice, providing an additional structural parameter beyond simple spacer length for tuning optoelectronic properties in 2D perovskite systems.
Enhanced Crystallization Quality Optimization: The modified phenethylammonium cation influences perovskite crystallization kinetics through altered intermolecular interactions, promoting improved film morphology with reduced defect density compared to unsubstituted PEABr.
Dual-Function Passivation with Dipole Modulation: 4MeO-PEABr simultaneously passivates grain boundary and surface defects through the ammonium head group while the methoxy-substituted aromatic tail modulates local electronic environment, combining structural and electronic passivation mechanisms.
Ultra-High Purity Exceeding 99%: Refined to >99% purity with low batch impurity content, the precursor minimizes extrinsic defects in 2D perovskite thin films and supports reproducible device performance across experimental batches.

APPLICATION SCOPE: Functionalized organic spacer cation for 2D Ruddlesden-Popper phase perovskite synthesis with dipole engineering. Crystallization quality optimization agent for perovskite thin films through modified intermolecular interactions. Surface and grain boundary passivation precursor with combined structural and electronic passivation mechanisms. Dipole modulation additive for tuning optoelectronic properties in layered perovskite structures. Compatible with spin-coating and solution blending deposition protocols. Supports two-dimensional perovskite solar cell, photodetector, and light-emitting device 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 4-methoxy-phenethylammonium bromide 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: 4-Methoxy-Phenethylammonium bromide 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 solid within an inert-atmosphere glovebox (H₂O < 1 ppm, O₂ < 1 ppm). This product does not have an assigned CAS number; refer to the catalog number MS300750 for ordering and documentation purposes. For detailed safety and handling information, consult the Safety Data Sheet prior to use.
