Product Description:

Ethyl 3-bromo-2-oxopropanoate is a bifunctional organic building block featuring a bromine atom at the 3-position and a ketone group adjacent to an ethyl ester. Its molecular formula is C5H7BrO3, and it is commonly used as a reactive intermediate in organic synthesis. This compound serves as a versatile alkylating agent and Michael acceptor due to the presence of both an electrophilic bromine and an ж┴,ж┬-unsaturated carbonyl system. It is widely employed in the synthesis of heterocycles, pharmaceutical intermediates, and agrochemicals. In medicinal chemistry, it is utilized to construct small-molecule drug fragments, particularly in the development of enzyme inhibitors and bioactive compounds. Due to its high reactivity, Ethyl 3-bromo-2-oxopropanoate should be handled with care, avoiding exposure to moisture and strong bases. It is typically stored under inert atmosphere and used in controlled laboratory or industrial settings.
