- Final product with stereochemistry
- Yields and selectivity data boxes
Use standard organic chemistry arrow conventions.

Left half (UPLC section): Draw a schematic diagram of a UPLC system, including
an autosampler, high-pressure pump, and chromatographic column with particle
packing visualization.

Right half (MS section): Show the mass spectrometer components including
ionization source (ESI), mass analyzer (quadrupole or TOF), and detector.

Connect both sections with the LC-MS interface. Label all major components
and show sample/solvent flow paths with arrows.
