Compounds that are complicated and varied are substances that come from refining petroleum. These compounds are manufactured and transported in large quantities, thus their potential risks and hazards are closely examined. Unique difficulties in terms of registration and evaluation occur due to the complexity and diversity of composition that are intrinsic to them. The best strategy to close data gaps and guarantee the safe use of these chemicals has been the subject of ongoing discussion between the industry and the decision-makers. The degree of chemical compositional characterization of petroleum refining products that may be required for substance identification and hazard assessment has been one of the more difficult topics. For complete characterization of petroleum substances and identification of the most abundant constituents, a number of unique analytical techniques can be applied. The application of analytical chemistry advancements to regulatory decision-making hasn’t been as clear, though. Therefore, the purpose of this review is to fill the gap between the demands and expectations of the decision-makers and the science of chemical characterization of petroleum. Mutual understanding of the regulatory requirements and the actual knowledge that these new methods may provide should make it easier to move forward with assuring the safety of petroleum refining’s end products.
