4,4-DIFLUORO-1,3,5,7,8-PENTAMETHYL-4-BORA-3A,4A-DIAZA-S-INDACENE Usage And Synthesis

Uses

Pyrromethene 546 is a hydrophobic compound that adsorbed strongly to the PDMS (poly(dimethylsiloxane)), indicating the hydrophobicity of the channel walls is clearly problematic for CZE analysis of hydrophobic analytes.

Description

BDP 493/503 is a green fluorescent borondipyrromethene dye for lipid labeling. It is used for cell membrane visualization in microscopy, as well as for staining and tracing of hydrophobic media.
