Fluorescein

Fluorescein

• CAS Number: 2321-07-5
• UNSPSC Description: Fluorescein (Uranine) is widely used as a fluorescent tracer in medicinal and biological applications and tumor infected tissues tracer. Fluorescein (Uranine) is a representative green fluorophore that has been widely used as a scaffold of practically useful green fluorescent probes[1][2].
