How predicted chromatographic retention can support degradation-product identification and stability-indicating analytical method development.
Retention-time prediction can provide an additional line of evidence when interpreting complex degradation profiles. It is most useful as a prioritization and hypothesis-support tool rather than a replacement for chromatographic validation.
Candidate ranking
When several structures have similar masses, retention behavior can help prioritize plausible identities.
Applicability domain
Predictions should be interpreted according to how well the compound is represented by the model.
Method development
Predicted relative behavior can help anticipate challenging co-elution or highly retained products.
Confirmation
Definitive identity requires appropriate analytical evidence, and reference standards may still be necessary.
Frequently asked questions
Can predicted retention identify a compound by itself?
No.
What is the main use?
Supporting candidate prioritization and analytical planning.
Why does applicability domain matter?
Outside-domain predictions are less supported by model experience.
Can it support stability-indicating methods?
Yes, as a complementary planning and interpretation tool.
