Cheminformatics, short for chemical informatics, is the use of computational methods to store, organise and transform chemical data. Sitting on the interface of computational chemistry and data science, cheminformatics has applications to many branches of chemistry, for example, small molecule drug discovery, materials chemistry, agrochemistry, and food science.
Where traditional chemistry primarily consists of in vitro experiments, cheminformatics primarily focusses on in silico aspects, often informed by or integrated with in vitro experiments. Although both traditional chemistry and cheminformatics are based on chemistry concepts, cheminformatics applies software and algorithms to manipulate these, to obtain results and predictions that may not otherwise be possible, practical or time/cost efficient to obtain.
Examples of techniques that commonly fall under the cheminformatics umbrella include storage and organisation of chemical information, structure-property predictions, virtual screening methods, similarity structural analysis, and the design of chemical compounds and libraries.
