4. Case Studies
Case 1: Pharmaceutical API Synthesis
Client: European CRO (Confidential)
Challenge: Low yield (32%) in brivanib alaninate intermediate synthesis
Solution: Replaced Pd(PPh3)4 with 3 mol% DIETHYL(3-PYRIDYL)BORANE
Result: 89% yield, reduced palladium residue to <0.5 ppm
Case 2: OLED Material Development
Client: Asian Materials Lab
Challenge: Inconsistent hole-transport layer performance
Solution: Used as dopant in carbazole-based matrix
Result: 18% improvement in device lifetime (LT80 @ 1000 cd/m²)
