Description

3-Bromo-2-Methyl-5-(Pentafluorosulfur)Aniline is a specialized fluorinated aniline derivative, distinguished by the presence of both bromine and a pentafluorosulfur (SF5) functional group. This unique molecular architecture makes it a high-value building block for advanced material science and pharmaceutical research, where its electronic and steric properties are leveraged to modulate activity and stability. It is primarily sought after by R&D chemists and process development scientists in the agrochemical, pharmaceutical, and specialty chemical sectors for synthesizing novel compounds with enhanced performance characteristics.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those targeting central nervous system (CNS) disorders or requiring fluorinated motifs for metabolic stability.
• Agrochemical Research: Used to develop novel herbicides, fungicides, and insecticides, where the SF5 group can impart unique biological activity and environmental persistence profiles.
• Liquid Crystal & OLED Materials: Acts as a building block for advanced electronic materials, where its polarizable structure contributes to the desired electro-optical properties in displays and semiconductors.
• Polymer Modification: Employed to introduce functional aniline groups into polymer backbones, creating specialty polymers with specific chemical resistance or surface properties.
• Ligand Synthesis for Catalysis: Utilized in the preparation of novel ligands for transition metal catalysts used in cross-coupling and other fine chemical synthesis reactions.
• Dye & Pigment Intermediate: Functions as a precursor for the synthesis of complex, high-performance dyes and pigments, especially where bromine and fluorine atoms are needed for color fastness and stability.

Quality Control

Every batch of 3-Bromo-2-Methyl-5-(Pentafluorosulfur)Aniline is produced and analyzed under strict quality management protocols. Our products undergo rigorous quality testing to ensure compliance with industry standards for identity, purity, and consistency. Certificates of Analysis (COA) detailing key parameters such as assay, impurity profile, and physical characteristics are available upon request.

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 consideration should be given to storage under an inert atmosphere for long-term preservation of quality.
