Ethyl 3-bromo-2-oxopropanoate(CAS: 70-23-5)

Ethyl 3-bromo-2-oxopropanoate (CAS: 70-23-5) is a white crystalline solid with a molecular weight of approximately 189.03 g/mol. It is sparingly soluble in water but miscible with common organic solvents. It is moderately reactive, particularly towards nucleophiles and bases. The compound is stable under normal conditions but should be stored in a cool, dark place to avoid photodegradation.

Ethyl 3-bromo-2-oxopropanoate (CAS: 70-23-5) can be synthesized via bromination of ethyl 2-oxopropanoate using N-bromosuccinimide (NBS) as a brominating agent under UV light. The reaction is typically performed in an inert atmosphere to prevent side reactions. The product is isolated by crystallization from an appropriate solvent.

Ethyl 3-bromo-2-oxopropanoate (CAS: 70-23-5) finds application in pharmaceuticals for the synthesis of certain intermediates and in organic synthesis for the formation of functional groups. It is also used in polymer chemistry as a monomer and in sensor technology for detecting specific analytes.

When handling Ethyl 3-bromo-2-oxopropanoate (CAS: 70-23-5), gloves and safety glasses should be worn. It is recommended to work in a fume hood due to its potential for generating toxic fumes. In case of skin contact, wash with soap and water, and in case of eye contact, flush with water for at least 15 minutes. Refer to the Safety Data Sheet (SDS) for detailed emergency procedures.
