What is 4,4-DIFLUORO-1,3,5,7,8-PENTAMETHYL-4-BORA-3A,4A-DIAZA-S-INDACENE?

The Uses of 4,4-DIFLUORO-1,3,5,7,8-PENTAMETHYL-4-BORA-3A,4A-DIAZA-S-INDACENE

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.

General Description

Difluoro{2-(1-(3,5-dimethyl-2H-pyrrol-2-ylidene-N)ethyl)-3,5-dimethyl-1H-pyrrolato-N}boron is an organoboron composed of dipyrromethene with a boron in the center. It is a fluorescent dye with a high quantum yield and an ability to absorb small molecules with sharp peaks in the ultraviolet region.
