Description

3,5-Bis(Bromomethyl)Pyridine HBr is a versatile brominated pyridine derivative that serves as a critical bifunctional building block in advanced organic synthesis. Its value lies in its dual reactive bromomethyl groups, which facilitate efficient cross-coupling and cyclization reactions to construct complex molecular architectures. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries developing new active compounds and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for kinase inhibitors and other small-molecule therapeutics.
• Agrochemical Synthesis: Building block for creating advanced fungicides, herbicides, and plant growth regulators with enhanced efficacy.
• Ligand and Catalyst Development: Used to construct sophisticated pyridine-based ligands for transition metal catalysis and coordination chemistry.
• Material Science Monomer: Serves as a functional monomer or cross-linking agent in the production of specialty polymers and advanced organic frameworks.
• Chemical Biology Probes: Employed in the design and synthesis of molecular probes and tags for studying biological systems.
• Custom Synthesis & Contract Manufacturing: A fundamental starting material for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) serving diverse R&D projects.

Quality Control

Our 3,5-Bis(Bromomethyl)Pyridine HBr is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, NMR for structural confirmation, and Karl Fischer titration for moisture content. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with customer specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation. Keep away from heat, sparks, and open flame.
