For any chemical compound to be effectively and safely utilized in industrial and research settings, a thorough understanding of its properties is essential. Methyl 2-bromo-2-methylpropionate (CAS 23426-63-3) is no exception. This versatile chemical, while highly useful as an organic synthesis intermediate and free radical initiator, possesses characteristics that necessitate careful handling and storage. Familiarity with its physical and chemical attributes ensures both operational efficiency and safety.

Methyl 2-bromo-2-methylpropionate is typically described as a colorless, clear liquid. Its molecular formula is C5H9BrO2, with a molecular weight of approximately 181.03 g/mol. Key physical properties include a density of around 1.399 g/cm³ and a boiling point of 145.8°C. Notably, its flash point is 49°C, which classifies it as a flammable liquid. This property dictates that it must be handled with care, away from ignition sources, and stored in well-ventilated areas. The information regarding methyl 2-bromo-2-methylpropionate applications often goes hand-in-hand with guidelines on its safe use.

Chemical stability is another critical aspect. When stored properly in a cool, ventilated place, Methyl 2-bromo-2-methylpropionate maintains its integrity and reactivity. However, exposure to excessive heat or moisture can potentially degrade its quality or affect its performance in sensitive reactions, such as ATRP. The compound's index of refraction, typically around 1.451, serves as an indicator of its purity. Maintaining high purity, often specified as ≥99.0% by GC, is crucial for consistent results in synthesis and polymerization.

Safe handling protocols are paramount. Due to its flammable nature and potential irritant properties, appropriate personal protective equipment (PPE) should always be used, including gloves, safety glasses, and lab coats. Proper ventilation in laboratories and storage areas is also crucial to prevent the buildup of flammable vapors. For companies like NINGBO INNO PHARMCHEM CO.,LTD., ensuring that customers are informed about these handling and storage requirements is a key part of their service. By adhering to these guidelines, users can confidently harness the significant potential of Methyl 2-bromo-2-methylpropionate in their diverse chemical processes.
