Formula:

C17H22ClN3

Basic Info

Auramine O is a diarylmethane dye used as a fluorescent stain. In its pure form, Auramine O appears as yellow needle crystals. It is very soluble in water and soluble in ethanol.
Auramine O can be used to stain acid-fast bacteria (e.g. Mycobacterium, where it binds to the mycolic acid in its cell wall) in a way similar to Ziehl-Neelsen stain. It can also be used as a fluorescent version of Schiff reagent.
Auramine O can be used together with Rhodamine B as the Truant auramine-rhodamine stain for Mycobacterium tuberculosis. It can be also used as an antiseptic agent.

Carcinogenicity

The Human Health Assessment Group in EPA's Office of Health and Environmental Assessment has evaluated auramine for carcinogenicity. According to their analysis, the weight-of-evidence for auramine is group B2, which is based on inadequate evidence in humans and sufficient evidence in animals. As a group B2 chemical, auramine is considered probably carcinogenic to humans. /Auramine/

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: no data available
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

Using an initial concn of 100 mg/L auramine hydrochloride, 0 %BOD was observed after a 2 week period in a biodegradation screening test using 30 mg/L sludge(1). Based on a five-day BOD value of 0.038 g/g determined in an aerobic aqueous screening test utilizing municipal waste activated sludge, a theoretical BOD value of 1.3% can be calculated for auramine hydrochloride(2,SRC).

12.3 Bioaccumulative potential

The BCF range for auramine hydrochloride was experimentally determined to be 3.8-16 in a flow-through test using carp, Cyprinus Carpio(1). This BCF value indicates that auramine hydrochloride will not bioconcentrate in fish(SRC).

12.4 Mobility in soil

Aromatic amines have been observed to undergo rapid and reversible covalent bonding with humic materials in aqueous solution; the initial bonding reaction is followed by a slower and much less reversible reaction believed to represent the addition of the amine to quinoidal structures followed by oxidation of the product to give an amino-substituted quinone; these processes represent pathways by which aromatic amines may be converted to latent forms in the biosphere(4). In the absence of covalent bonding, one can estimate the adsorption potential based on the Koc value. Based on an experimental water solubility of 10,000 mg/L(2) and a recommended regression-derived equation(1), the Koc value for auramine hydrochloride can be estimated to be 27(SRC). According to a suggested classification scheme(3), this Koc value indicates that auramine hydrochloride will have very high soil mobility. However, using a structure estimation method(5), Koc values of 50,000 and 25,000 can be estimated for auramine hydrochloride and its parent compound, respectively, and these Koc values indicate that auramine hydrochloride will be immobile in soil(3,SRC).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
