Description

Pyridine,3,5-Dibromo-4-(Trimethylsilyl)-(9Ci) is a specialized organosilicon and halogenated pyridine derivative, serving as a high-value synthetic intermediate. This compound is engineered to introduce both bromine and trimethylsilyl functional groups in a single, precise molecular architecture, enabling advanced chemical synthesis. It is primarily utilized by research chemists and process development scientists in the pharmaceutical and agrochemical industries for constructing complex molecules, such as active pharmaceutical ingredients (APIs) and novel crop protection agents.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of complex drug candidates, particularly those requiring halogenated or silylated heterocyclic cores.
• Agrochemical Research: Used in the development of new herbicides, fungicides, and insecticides where the bromine atoms and silicon group confer specific biological activity and stability.
• Material Science Precursor: Serves as a monomer or functionalization agent in the creation of advanced polymers, liquid crystals, and organic electronic materials.
• Cross-Coupling Reactions: Acts as a substrate in palladium-catalyzed reactions (e.g., Suzuki, Stille) where the bromine atoms serve as excellent leaving groups for carbon-carbon bond formation.
• Organometallic Chemistry: Used to prepare ligands for catalysis or as a starting material for further functionalization via lithiation or other metal-halogen exchange reactions.
• Chemical Synthesis Reagent: Provides a protected or masked functionality in multi-step synthetic routes within fine chemical and academic research laboratories.

Quality Control

Our Pyridine,3,5-Dibromo-4-(Trimethylsilyl)-(9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of research and development applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your specifications.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
