Description

4-Bromo-3-Methylaniline Hydrochloride is a high-purity organic intermediate in the form of its stable hydrochloride salt. This compound is essential for the synthesis of complex molecules, offering a crucial halogenated aniline building block for pharmaceutical and agrochemical research and development. It is primarily utilized by R&D chemists and process development scientists in the fine chemical, pharmaceutical, and crop protection industries to introduce specific bromine-substituted aromatic motifs into target structures.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules requiring a brominated aniline moiety.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides where its specific substitution pattern is critical for biological activity.
• Dye and Pigment Manufacturing: Serves as a precursor in the creation of specialized azo dyes and organic pigments, contributing to color fastness and specific hue properties.
• Ligand and Catalyst Development: Employed in organic and organometallic chemistry to create novel ligands for catalytic systems or as a scaffold in material science research.
• Life Science Research: Used as a biochemical tool and reagent in academic and industrial laboratories for probing biological mechanisms and developing diagnostic agents.
• Custom Synthesis and Contract Manufacturing: A vital starting material for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) producing client-specific fine chemicals.

Quality Control

Our 4-Bromo-3-Methylaniline Hydrochloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, identity confirmation by IR and NMR spectroscopy, and residual solvent analysis, to ensure it meets the stringent requirements of our global clientele. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability, consistency, and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
