​​CAS 877-37-2 for Organic Synthesis

2-Bromo-4-chloropropiophenone CAS 877-37-2 is a halogen-substituted α-bromo ketone that functions as a ​specialized chemical intermediate. It is structurally analogous to its isomer 2-bromo-3'-chloropropiophenone but distinguished by the position of the chlorine atom on the aromatic ring. Due to its high reactivity, it is a valuable building block in organic synthesis, particularly in the formation of C–N bonds and heterocycles, and is subject to stringent regulatory control.
