Sequence-Confirmed Synthesis — Why Mass Spec Alone Isn't Enough

ESI-MS on the lot report confirms a molecular weight, not a sequence. Where the gap matters, why isobaric pairs and chain-order swaps slip through, and the two analytical add-ons that actually prove sequence — LC-MS/MS fragmentation and Edman degradation.
