Introduction to Chemical Structure Search
What is Chemical Structure Search?
Chemical structure or molecular structure search is a specialized 
technique used to identify compounds based on their molecular 
composition or substructure.
Why It Matters:
● Enables accurate identification of known and novel compounds
● Essential in patent analysis, novelty assessment, and freedom 
to operate (FTO)
● Critical for pharma, biotech, agrochemicals, and materials 
science industries

Applications of Chemical Structure Search
Industries and Use Cases:
● Pharmaceuticals: Drug discovery, prior art, and competitor 
molecule analysis
● Agrochemicals: Structural comparison of pesticides and herbicides
● Chemical Manufacturing: Patent landscaping for process 
optimization
● Academic Research: Structure-based literature review and citation 
tracking
Key Search Types:
● Exact structure search
● Substructure search
● Similarity search
● Markush structure search
