4,4-Difluoro-1,3,5,7,8-pentamethyl-4-bora-3a,4a-diaza-s-indacene Chemical Properties,Usage,Production

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.

Uses

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.
