Label Stability
- Overall
- Low risk
- Calculation reliability
- Medium, some information should be confirmed
- Carbon-bound deuterium is evaluated by local chemical environment; isotope effects should still be checked experimentally.
Internal Standard Suitability
- Rating
- High
- Chromatographic similarity
- Possible isotope effect
- Natural isotope overlap
- Low
- Exact mass separation is 3.01883 Da; MS channel separation should be verified in the final method.
- The unlabeled parent mass was derived from the isotope structure because a curated parent structure was not matched.
- Overall suitability: High.
