1H NMR assignment for synthetic products is a ChemistryAtlas synthesis guide card for characterization and proof of structure. It focuses on confirming identity, purity, stereochemistry, and impurities.
- Start with the linked source: NMRShiftDB.
- Compare at least two literature precedents before using the chemistry on a valuable substrate.
- Record reagent equivalents, concentration, temperature, atmosphere, time, workup, purification, yield, and characterization.
- When this topic is useful in a synthesis plan.
- Which variables usually control success or failure.
- What evidence is needed before trusting the product assignment.
Characterization expectation: use this card as the primary structure-proof workflow and document raw data, assignments, and purity criteria.
Safety expectation: review SDS and incompatibilities, keep scale conservative during scouting, and document quench and waste handling before running the reaction.
Recommended level: graduate researcher. Resource type: characterization workflow.
