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 providing consistent and reliable calibration for trace-level analysis. Also used in research studies focused on assessing exposure risks and evaluating water treatment processes.
