Used as a reference standard in environmental testing laboratories to calibrate analytical instruments for the detection and quantification of 1,2,3-trichloropropane in water, soil, and air samples. Commonly employed in gas chromatography and mass spectrometry (GC-MS) analyses to ensure accurate measurement of this contaminant, especially in regulatory compliance testing. Helps monitor industrial emissions and assess groundwater contamination, particularly near sites involved in pesticide manufacturing or solvent use. Also utilized in research studies focused on pollutant degradation and remediation technologies.
