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 methods to ensure accurate measurement of trace contaminants, especially in groundwater monitoring and remediation projects. Also utilized in regulatory compliance testing to meet EPA and other environmental safety guidelines. Its precise concentration allows for reliable calibration curves and quality control in analytical procedures.
