Annotator input notes

Orthogonal identity package for an asymmetric ketone reduction product

The isolated material came from asymmetric reduction of a bromo-methoxy acetophenone. Eight same-formula candidate regioisomers/enantiomers are supplied. Atom numbering is defined in analysis_config.json. The NMR package contains processed peak lists and correlation picks rather than vendor binary spectra; no atom assignment is embedded in those tables.

Chiral HPLC includes a racemic bracket, a certified R reference, three product injections, and two product-plus-R-reference spikes. Peak labels A and B are chromatographic labels only. U1 is a resolved non-enantiomer impurity and must not enter the enantiomer normalization.

qNMR was acquired under long-delay conditions with dimethyl sulfone as internal standard. The starting ketone reference has both a carbonyl methyl signal and a methoxy signal. Product and starting ketone methoxy resonances are not resolved in the assay spectra; the integration table does not supply an exclusion or truth label.

The dataset contains realistic mass drift, isotope-ratio variation, retention-time drift, injection-area variation, weighing variation, and integration noise. It is a physics- and metrology-based simulation informed by public NMR, chiral HPLC, and qNMR practice. It contains no private compound, laboratory, organization, or proprietary method data.
