Application and positioning

A densely functionalised imidazo[1,5-a]pyrazine: 8-amino and 1-bromo on the core, a Cbz-protected pyrrolidine at C-3. The bromine is the late-stage coupling site, and the Cbz comes off by transfer hydrogenation without touching the aryl bromide. Laurand supplies it from audited Chinese producers in kilogram to multi-hundred-kilogram lots; process and regulatory documentation is coordinated case by case with the manufacturing site.

Quality and documentation

  • Batch-specific Certificate of Analysis with HPLC purity and a full impurity profile
  • Chiral purity by chiral HPLC where the molecule carries defined stereocentres
  • Residual solvent data against ICH Q3C and elemental impurity data against ICH Q3D on request
  • Structure confirmation by NMR and MS on first shipments
  • SDS in the language of your market, with GHS classification for the destination

Packaging and handling

  • 1 kg, 5 kg and 25 kg fibre drums with inner PE liner; amber glass bottles for gram quantities
  • Sealed, dry and protected from light; cold-chain arrangement discussed per product where the intermediate requires it
  • Store at ambient temperature in a dry warehouse, away from oxidising agents and moisture
