INCHI, THE INTERNATIONAL TEXT CHEMICAL IDENTIFIER, AS A PROSPECTIVE TOOL FOR FORENSIC EXAMINATION ON INTELLECTUAL PROPERTY

Abstract

In the field of chemical informatics, the development of information technologies offers various products that can make forensic experts in the field of intellectual property related to chemical compounds productive and more convincing for court participants, who do not have special knowledge in the field of chemistry, pharmaceuticals, and related industries. International Text Chemical Identifier InChI and its abbreviated derivative InChIKey is one such useful tool. The advantages of using the InChI international textual chemical identifier are shown here, using an example taken from judicial practice, when conducting a forensic examination or research, for example, for comparison and identification of chemical compounds. InChI and InChIKey are also useful for searching for documents, which are necessary for explanations in court and for more visual substantiation of the conclusion of a forensic expert. This article details the algorithm for generating InChI and InChIKey. There are also links to free information resources with which you can download software or use this method directly on the site to solve various problems that occur during forensic examinations or expert studies in the field of intellectual property. In a particular case, the evidence for trial participants who do not have special knowledge in chemistry, the results of comparing two chemical formulas that are depicted in different styles of chemical formulas, show the advantages of InChI. In contrast to the rather complicated procedure for the equation of two-dimensional chemical formulas of such three-dimensional objects as molecules, after generating the corresponding InChI, the task is transformed into equations of two lines of characters, it is easy to perform using the search function of any text editor, for example, Word, or even a simple comparison. It also briefly describes the use of InChIKey for the efficient search for scientific and technical publications. The material presented in the article will allow even readers without a chemical education to take the first steps in mastering such a modern tool as InChI. International Text Chemical Identifier InChI is a useful tool with great prospects for specialists in various fields of knowledge and, in particular, for forensic experts in the field of intellectual property.
