4,7-diphenyl-1,10-phenanthroline (CAS 1662-01-7)

Application and positioning

Bathophenanthroline: the classic colorimetric reagent for iron and a ligand for copper and ruthenium complexes. It carries no reactive handle — it is a ligand and a standard, not a building block. Laurand supplies it from audited Chinese producers in kilogram to multi-hundred-kilogram lots, with the documentation your market requires.

Quality and documentation

• Batch-specific Certificate of Analysis with HPLC or GC purity and a full impurity profile
• Trace metal report (Pd, Fe, Cu) on request — residual catalyst is what limits OLED device lifetime
• Water content by Karl Fischer and residual solvent data for solution-processed grades
• SDS in the language of your market, with GHS classification for the destination
• Pre-shipment sample for laboratory approval on first orders

Packaging and handling

• 1 kg, 5 kg and 25 kg fibre drums with inner PE liner; amber glass bottles for gram to kilogram quantities on request
• Sealed and protected from light — aromatic OLED intermediates discolour under prolonged UV exposure
• Store at ambient temperature in a dry, dark warehouse, away from strong oxidising agents
