Description

3,4-Dimethylbenzylbromide CAS NO 94416-66-7 is a versatile benzyl bromide derivative, a key alkylating agent and synthetic intermediate in advanced organic synthesis. Its value lies in providing a reactive benzylic bromide moiety adjacent to a dimethyl-substituted aromatic ring, enabling the introduction of the 3,4-dimethylbenzyl group into target molecules. This compound is essential for researchers and process chemists in the pharmaceutical, agrochemical, and specialty chemical industries developing new active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Crucial for the synthesis of novel drug candidates, particularly in constructing complex molecules for oncology, CNS, and metabolic disease research.
• Agrochemical Synthesis: Serves as a building block for developing new herbicides, fungicides, and insecticides, leveraging the 3,4-dimethylbenzyl moiety for enhanced bioactivity.
• Ligand and Catalyst Preparation: Used in the preparation of specialized phosphine ligands or organometallic catalysts for asymmetric synthesis and cross-coupling reactions.
• Material Science Research: Acts as a monomer or functionalization agent in the development of advanced polymers, liquid crystals, and organic electronic materials.
• Fine Chemical Production: Employed in the multi-step synthesis of dyes, flavors, fragrances, and other high-value specialty chemicals.

Quality Control

Our 3,4-Dimethylbenzylbromide is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and Karl Fischer titration, to ensure high purity and consistent performance. We provide detailed Certificates of Analysis (COA) with every shipment, documenting identity, assay, and impurity profiles. Our quality commitment supports compliance with cGMP and ICH guidelines for pharmaceutical development.

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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong acids and incompatible materials.
