For professionals working with chemical compounds, a thorough understanding of their properties and safety protocols is fundamental to successful and secure operations. 4-Bromo-3-methylaniline (CAS 6933-10-4) is an important organic intermediate with specific characteristics that dictate its handling and application. This article provides an in-depth overview of its properties and essential safety considerations for B2B users, researchers, and procurement specialists.

4-Bromo-3-methylaniline, with the molecular formula C7H8BrN and a molecular weight of 186.05 g/mol, presents as a grey to brownish crystalline powder. Its melting point typically ranges between 79-83°C, and its boiling point is around 240°C. These physical attributes are important for storage and processing. The compound is generally available at a purity of 97% or higher, ensuring its suitability for demanding synthetic procedures. Key identifiers include its CAS number, 6933-10-4, and EINECS number 230-056-3. Manufacturers often list a predicted pKa value, such as 4.02±0.10, providing further chemical context.

Safety is a paramount concern when handling any chemical. 4-Bromo-3-methylaniline is classified with hazard statements indicating it can cause skin irritation (H315), serious eye irritation (H319), and may cause respiratory irritation (H335). It is also harmful if swallowed (H302), in contact with skin (H312), or if inhaled (H332). Therefore, it is crucial to always use appropriate personal protective equipment (PPE) when handling this substance. This includes wearing chemical-resistant gloves, protective clothing, eye protection (such as safety goggles or a face shield), and ensuring adequate ventilation or using respiratory protection if exposure is likely.

When sourcing 4-Bromo-3-methylaniline, it is advisable to buy from reputable manufacturers and suppliers who provide comprehensive Safety Data Sheets (SDS). These documents detail the hazards, safe handling procedures, first-aid measures, and disposal considerations. NINGBO INNO PHARMCHEM CO.,LTD., as a leading supplier, ensures that all relevant safety information is accessible. Understanding storage conditions, such as keeping the material in a dark, dry, and sealed place at room temperature, is also vital for maintaining product integrity and safety.

In summary, 4-Bromo-3-methylaniline is a valuable intermediate with well-defined properties. By adhering strictly to safety guidelines, utilizing appropriate PPE, and sourcing from trusted manufacturers, professionals can confidently and safely incorporate this compound into their research and production processes. Prioritizing safety ensures the well-being of personnel and the integrity of operations.
