Description

1-Azido-4-Bromobenzene is a versatile bifunctional aromatic compound that serves as a critical building block in advanced organic synthesis. Its unique combination of an azido group and a bromo substituent on a benzene ring makes it an invaluable precursor for click chemistry and cross-coupling reactions. This high-value intermediate is primarily sought by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and materials science industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel active pharmaceutical ingredients (APIs) via Huisgen 1,3-dipolar cycloaddition (click chemistry).
• Agrochemical Synthesis: Building block for creating new herbicides, fungicides, and insecticides with tailored properties.
• Polymer & Materials Science: Used to functionalize polymers, dendrimers, and surfaces, introducing azide handles for further modification.
• Bioconjugation & Probe Development: Enables site-specific labeling of biomolecules (proteins, oligonucleotides) for diagnostics and biochemical research.
• Ligand & Catalyst Preparation: Serves as a starting material for synthesizing specialized ligands and organometallic catalysts.
• Academic & Industrial R&D: Fundamental reagent for methodological development in organic chemistry and drug discovery programs.

Quality Control

Every batch of 1-Azido-4-Bromobenzene is manufactured and tested under strict quality management protocols to ensure consistency and reliability for your critical syntheses. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing purity, identity, and impurity profiles. Our quality systems are designed to support cGMP and ISO standards for advanced chemical intermediates, ensuring traceability and compliance for regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its properties of being highly volatile and easily oxidized, it is recommended to store this material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, open flames, and incompatible materials.
