Applications
Dibromochloromethane was formerly used as a flame retardant and as an intermediate in chemicals manufacturing. Today it is used only as a laboratory reagent. Dibromochloromethane is also a disinfection byproduct, formed by the reaction of chlorine with natural organic matter and bromide ions in the raw water supply. As a result, it is commonly found in chlorinated drinking water.
Also, it is able to reduce methane production in ruminants by 79 %[https://www.researchgate.net/publication/299274346_Identification_of_bioactives_from_the_red_seaweed_Asparagopsis_taxiformis_that_promote_antimethanogenic_activity_in_vitro Identification of bioactives from the red seaweed Asparagopsis taxiformis that promote antimethanogenic activity in vitro]
