Rhodamine B *CAS 81-88-9*

Rhodamine B (also called Rhodamine 610, Basic Violet 10, or C.I. 45170) is used as a fluorescent staining dye, sometimes in combination with auramine O. The auramine-rhodamine stain is used to demonstrate acid-fast organisms, notably Mycobacterium; Rhodamine B is tunable around 610 nm when used as a laser dye.
