Description

Pyridiniumhydrobromideperbromide (CAS NO 66323-10-2) is a versatile and highly effective brominating agent widely used in organic synthesis. Its primary value lies in its ability to selectively brominate alkenes and alkynes under mild conditions, offering a safer and more controllable alternative to elemental bromine. This reagent is essential for research chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries seeking efficient halogenation pathways.

Application

• Pharmaceutical Intermediate Synthesis: Key reagent for the bromination of sensitive substrates in the production of active pharmaceutical ingredients (APIs).
• Agrochemical Manufacturing: Used in the synthesis of brominated herbicides, fungicides, and other crop protection agents.
• Fine Chemical Production: Facilitates selective bromination reactions in the manufacture of dyes, fragrances, and specialty chemicals.
• Academic & Industrial R&D: A staple bromine source for method development and exploratory synthesis in laboratory settings.
• Polymer Chemistry: Employed in the modification of polymers and the synthesis of brominated flame retardants.
• Material Science: Used in the surface functionalization and creation of brominated precursors for advanced materials.

Quality Control

Our Pyridiniumhydrobromideperbromide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay, purity profiling, and identification, to ensure it meets the high standards required for synthetic applications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation. Keep away from incompatible materials such as strong reducing agents and combustible organics.
