D-BIOTIN P-NITROPHENYL ESTER Usage And Synthesis
  • Chemical PropertiesWhite to off-white powder
  • Purification MethodsThe ester has been recrystallised by dissolving 2g in 95% EtOH (30mL), heated to dissolve, then cooled in an ice-water bath. The crystals are collected, washed with ice-cold 95% EtOH (5mL) and dried over P2O5. The RF on silica plates (CHCl3/MeOH 19:1) is 0.19 [Bodanszky & Fagan J Am Chem Soc 99 235 1977].
