How is 2-Bromo-4-chloro-1-nitrobenzene (CAS: 63860-31-1) typically synthesized?

2-Bromo-4-chloro-1-nitrobenzene can be synthesized through the nitration of 4-chlorobromobenzene. The reaction typically involves the use of concentrated nitric acid and sulfuric acid as a catalyst. The process requires careful control of temperature and concentration to achieve high selectivity and yield. This method is commonly used in academic and industrial settings for the preparation of this aromatic compound.
