Used as a reference standard in analytical laboratories for the calibration of instruments such as gas chromatographs (GC) and high-performance liquid chromatographs (HPLC). Ensures accurate identification and quantification of isopropylamine in environmental samples, industrial hygiene testing, and quality control processes. Commonly applied in the analysis of pesticide residues, pharmaceutical intermediates, and chemical manufacturing byproducts where isopropylamine may be present as a reagent or degradation product. Also utilized in research settings for method development and validation.
