Description

4-Bromoisophthalaldehyde is a versatile aromatic dialdehyde building block, distinguished by the strategic bromine substituent on the isophthalaldehyde core. This compound is valued for its dual aldehyde functionality, which provides two reactive sites for condensation, cyclization, and polymer formation, enabling the synthesis of complex molecular architectures. It is a critical intermediate for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, particularly in the development of ligands, organic semiconductors, and heterocyclic compounds.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), especially for molecules containing brominated aromatic or heterocyclic scaffolds.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and plant growth regulators that require brominated aromatic components.
• Organic Ligand & MOF Construction: Serves as a versatile linker for constructing metal-organic frameworks (MOFs) and coordination polymers due to its two aldehyde groups.
• Polymer & Resin Chemistry: Acts as a monomer or cross-linking agent in the production of specialty polymers, epoxy resins, and high-performance materials.
• Chemical Research & Development: Fundamental building block in organic synthesis for creating complex molecules, dyes, and fluorescent probes.
• Material Science: Used in the development of organic electronic materials, such as organic light-emitting diodes (OLEDs) and semiconductors.

Quality Control

Our 4-Bromoisophthalaldehyde is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high purity and batch-to-batch consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical parameters. Our commitment to quality supports compliance with cGMP and ISO 9001 standards for research and industrial use.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended long-term storage temperature is 2-8°C. Due to its sensitivity to light and oxidation, the container should be kept sealed and allowed to reach ambient temperature before opening to minimize moisture ingress.
