Description

Phosphorus Oxybromide is a versatile and highly reactive inorganic reagent, primarily used as a potent brominating and phosphorylating agent in organic synthesis. Its reactivity makes it a critical intermediate for introducing bromine or phosphorus-containing functional groups into complex molecular structures. This compound is essential for research and production in the pharmaceutical, agrochemical, and specialty chemical industries, where precise chemical transformations are required.

Application

• Pharmaceutical Intermediate Synthesis: Key reagent for the bromination of alcohols and carboxylic acids, and in the preparation of active pharmaceutical ingredients (APIs).
• Agrochemical Manufacturing: Used in the synthesis of herbicides, pesticides, and other crop protection agents that require brominated or phosphorylated structures.
• Flame Retardant Production: Serves as a precursor in the manufacture of brominated and phosphorus-based flame retardants for polymers and textiles.
• Organic Synthesis & Research: Employed in laboratories for dehydrating agents, cyclization reactions, and the synthesis of novel organic compounds.
• Liquid Crystal & Electronic Chemicals: Used in the production of intermediates for liquid crystal displays (LCDs) and other electronic materials.
• Polymer Modification: Facilitates the introduction of bromine or phosphate groups to modify polymer properties.

Quality Control

Our Phosphorus Oxybromide is manufactured under strict quality control protocols to ensure high purity and batch-to-batch consistency. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing key parameters such as assay, impurity profile, and physical characteristics. Our quality management system is designed to meet the stringent requirements of industrial and research applications, ensuring reliable performance in your 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 and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Recommended storage temperature is 2-8°C for long-term stability.
