Common Pitfalls in Chemical Structure Search and How to Fix Them?
Picture this: you’ve got a promising molecule, and either a patent filing or a product investment is on the horizon. Before anything else, you have to find out whether someone has already put it, or something like it, into the public record. A fast compound-name query won’t reliably tell you. Weaknesses in how you search can leave the most relevant documents undiscovered. A well-designed chemical structure search narrows those weaknesses, and the seven errors outlined below are where many searches fall short. 1. Depending on a Single Compound Name Compounds seldom go by just one name. Documents may refer to the same substance using its systematic name, a popular name, a brand name, or a code assigned in a lab. Pick one, and you’ll never see the documents that picked another. Try this instead: Assemble a full set of synonyms and identifiers up front. Use them for keyword queries, and add a structure search alongside, since patents often present compounds in drawings or generic...
