rhodamine B

CAS No.

81-88-9

Formula:

C28H31ClN2O3

Basic Info

Rhodamine B is a chemical compound and a dye. It is often used as a tracer dye within water to determine the rate and direction of flow and transport. Rhodamine dyes fluoresce and can thus be detected easily and inexpensively with instruments called fluorometers. Rhodamine dyes are used extensively in biotechnology applications such as fluorescence microscopy, flow cytometry, fluorescence correlation spectroscopy and ELISA.
Rhodamine B is used in biology as a staining fluorescent dye, sometimes in combination with auramine O, as the auramine-rhodamine stain to demonstrate acid-fast organisms, notably Mycobacterium.
Rhodamine B is tunable around 610nm when used as a laser dye. Its luminescence quantum yield is 0.65 in basic ethanol, 0.49 in ethanol, 1.0, and 0.68 in 94% ethanol. The fluorescence yield is temperature dependent.

General advice

Consult a physician. Show this safety data sheet to the doctor in attendance.

If inhaled

If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.

In case of skin contact

Wash off with soap and plenty of water. Consult a physician.

In case of eye contact

If swallowed

Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.

4.2 Most important symptoms/effects, acute and delayed

no data available

4.3 Indication of immediate medical attention and special treatment needed, if necessary

In treatment of eyes contaminated with cationic dyes, first aid measures are aimed at getting rid of dye which has not reacted with the tissues. This includes copious irrigation, mechanical removal of particles, and in the case of imbedded colored pencil may necessitate surgical exploration and careful removal of the particles. Solutions of tannin or tannic acid precipitate cationic dyes and render them essentially noninjurious, but this disposes of only that portion of the dye which has not already reacted with the tissues. /It was/ determined experimentally that a 5% to 10% solution of tannin was effective essentially in a prophylactic sense if applied within three minutes following application of powdered basic dyes to the eyes of rabbits, but that the effectiveness of this treatment rapidly diminished after three minutes. Other forms of chemical treatment have been aimed at removing both combined and excess dye. However, studies of the reaction of cationic dyes with cornea in vitro have shown these dyes to bind very tenaciously and to be very difficult to remove from combination with the tissue. ... /Cationic dyes/
