chemical fingerprint

Substance's unique pattern

A chemical fingerprint is a distinctive pattern of compounds or molecular characteristics that identifies a substance, much like a human fingerprint identifies a person.

Scientists use chemical fingerprints to trace the origin of materials, detect contamination, or authenticate products: The oil spill's chemical fingerprint matched the tanker's cargo.

The term applies across fields—forensics, environmental science, food safety, pharmaceuticals.
