NO-P-76 is an NMR sample label from the 9076 project, not a confirmed experiment. In the structured records it exists as a STUB record (exp-9076-000NOP76) — an unlinked sample named only from the file names of six NMR plots (1H and 13C FS + ZOOM1/ZOOM2, all dated 30SEP25, acquired on 20250930 in CDCl3), with no materials, process steps, batch, or outcome on file.

So to the "what is it" half: it is a sample (per the Bruker data-parameters block, "NAME Sample NO-P-76") analyzed by NMR on 2025-09-30. To the "which batch made it" half: the records do not contain a batch link for NO-P-76 — there is no ELN row, no summary-table row, and no batch ID tying this sample to a 9076 batch, and the sample does not appear in any other document in the drop. That missing link is a genuine gap, not something I can fill.
