Why a purity percentage cannot replace identity evidence

A purity percentage does not, by itself, identify the compound responsible for the principal signal. A result can be highly concentrated in one measured signal without that number establishing the intended molecular identity.

For research use only. Not for human or veterinary use.

Read the identity evidence independently. If the document supplies only a purity figure, describe only that result. Linking to a general compound reference does not turn a missing sample-specific identity test into a reported one.

Reading checklist

Find the sample-specific identity statement
Distinguish reference chemistry from measured evidence
Limit the summary to what the document reports

Reference: LC-MS identity evidence.
