Used as a reference standard in environmental testing laboratories to calibrate analytical instruments for the detection and quantification of bromodichloromethane in water samples. Commonly applied in gas chromatography and mass spectrometry methods to ensure accurate measurement of disinfection byproducts formed during chlorination of drinking water. Helps maintain compliance with regulatory standards by enabling precise monitoring of contaminant levels. Also used in research studies assessing the formation, fate, and health effects of halogenated organic compounds in aquatic systems.
