Carbon tetrachloride is a high-purity solvent (99%) specially formulated for use in infrared oil gauging and spectroscopy applications. It is primarily used in industrial and laboratory settings as a solvent for oils, fats, resins, and rubber due to its non-polar properties. Historically, it was employed in the production of refrigerants, propellants for aerosol cans, fire extinguishers, and as a cleaning agent for machinery and electronics. However, these applications have significantly declined and are restricted in many countries due to its toxicity, ozone-depleting potential, and environmental impact. In modern laboratories, it serves as a reagent for chemical reactions, particularly in organic synthesis, and as a medium for infrared (IR) spectroscopy, where its low absorption in the 2800-3200 cm⁻¹ region makes it ideal for analyzing oil content and other samples under strict safety controls.
