Reaction Scheme, Safety Precautions, Critical Process Parameter table, Optimized Reaction Conditions, and Conclusion sections are empty/absent, so no conclusion or outcome was emitted. In the embedded text layer the Epomine row ran together as 'Epomine SP01830'; the OCR page table (ocr/LBN 51/LBN 51_0.md) resolves it to name 'Epomine SP-018' with quantity 30. Scientist field not printed. Procedure step 2 remarks say '75-8 deg C' verbatim (temp column reads 75-80)."
