Product Features
Features of MS Fragmenter
- Predict MS fragmentation pathways based on established literature rules
- Estimate fragments for molecules up to 255-atoms large (excluding hydrogen atoms)
- Get results tailored to your experiment with extensive filtering options. Filter by:
- Positive or negative ionization
- Common reactions (resonance reactions, ring formation, and hydride shift)
- Distonic-ion formation (hydrogen shift, double-bond cleavage, triple-bond cleavage, saturated-ring cleavage)
- Type of bond cleaved (acrylic, non-aromatic, C-het aromatic, C-het cyclic)
- Hydrogen rearrangements, skeletal rearrangements, oxygen loss, and neutral losses
- Review the prediction rules to learn about the mechanics behind fragmentation
