Description

4-(4-Bromo-Butoxy)-Benzaldehyde is a versatile organic building block characterized by its benzaldehyde core functionalized with a bromoalkoxy chain. This bifunctional structure, featuring both an aldehyde group and a terminal bromine, makes it a critical intermediate for synthesizing more complex molecules through nucleophilic substitution and condensation reactions. It is primarily sought after by research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors for constructing novel compounds and fine-tuning molecular properties.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules requiring specific ether-linked side chains or aldehyde-derived functional groups.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and plant growth regulators where the bromobutoxy moiety can be further elaborated.
• Liquid Crystal & OLED Material Research: Serves as a building block for creating mesogenic cores and electron-transport materials in display and lighting technologies.
• Polymer & Resin Modification: Employed to introduce aldehyde functionality into polymers for cross-linking or to create specialty resins with tailored properties.
• Organic Synthesis & Chemical Research: A valuable reagent for constructing complex organic frameworks in academic and industrial R&D settings.

Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Standard analytical techniques, including HPLC, GC, and NMR, are employed to verify identity, purity, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container should be kept tightly sealed when not in use to minimize exposure to atmospheric moisture.
