Description

Phosphorus Pentabromide (CAS NO 7789-69-7) is a highly reactive inorganic bromide source, primarily valued for its powerful bromination capabilities in organic synthesis. Its significance lies in its ability to efficiently introduce bromine atoms into target molecules, a critical step in the production of pharmaceuticals, agrochemicals, and specialty chemicals. This reagent is essential for research chemists and process development scientists in the fine chemical, pharmaceutical, and material science industries seeking reliable and effective brominating agents.

Application

• Bromination Reagent in Organic Synthesis: A key reagent for electrophilic bromination reactions, converting alcohols to alkyl bromides and facilitating aromatic bromination.
• Pharmaceutical Intermediate Manufacturing: Used in the synthesis of active pharmaceutical ingredients (APIs) and complex drug molecules requiring bromine functional groups.
• Agrochemical Production: Employed in the creation of brominated herbicides, pesticides, and fungicides.
• Catalyst and Lewis Acid: Functions as a strong Lewis acid catalyst in various organic transformations and polymerization initiators.
• Material Science Research: Used in the synthesis of brominated flame retardants and specialty polymers.
• Laboratory Reagent: Serves as a fundamental bromine source for research and development in academic and industrial laboratories.

Quality Control

Our Phosphorus Pentabromide is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high chemical purity. We adhere to relevant industry standards for reagent-grade chemicals. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee product integrity and support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere such as argon or nitrogen to prevent decomposition. Recommended storage temperature is 2-8°C for long-term stability.
