Auramine can cause cancer according to an independent committee of scientific and health experts.
C.i. solvent yellow 34 appears as yellow crystalline powder or yellow needles. Auramine O free base is a member of the class of imines that is benzophenone imine carrying two dimethylamino substituents at positions 4 and 4'. The hydrochloride salt is the biological stain 'auramine O' It has a role as a fluorochrome and a histological dye. It is an imine, a tertiary amino compound and a substituted aniline. It is a conjugate base of an auramine O(1+). An aniline dye used as a disinfectant and an antiseptic agent. It is weakly fluorescing and binds specifically to certain proteins. Mechanism of Action ALTHOUGH THE REQUIREMENT FOR METABOLIC ACTIVATION REGARDING AURAMINE IS UNRESOLVED, IT IS CONSIDERED TO BE A PRO-CARCINOGEN. IT POSSESSES METHYLATED AMINO GROUPS. IT WILL UNDERGO RESONANCE CONJUGATION RENDERING THE AMINO N ATOM POSITIVELY CHARGED & THUS MORE PRONE TO HYDROXYLATION. THE DIRECT ACTIVITY OF AURAMINE VARIOUSLY REPORTED MAY BE DUE TO WEAK ELECTROPHILICITY AT THE UNSUBSTITUTED POSITIVELY CHARGED CENTRAL N ATOM IN THE OTHER EXTREME RESONANCE FORM. Therapeutic Uses ... IN THE UNITED KINGDOM ... AURAMINE HAS COME INTO PROMINENCE AS A POWERFUL ANTISEPTIC FOR USE IN NOSE & EAR SURGERY. ... A SPECIALLY PURIFIED AURAMINE, SOLD UNDER NAME OF GLAURAMINE, IS USED AS AN ANTISEPTIC IN THE TREATMENT OF GONORRHEA. /FORMER USE/ |

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

Oral Formulation 3: Dissolved in PEG400 (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 3.7401 mL | 18.7007 mL | 37.4014 mL | |
| 5 mM | 0.7480 mL | 3.7401 mL | 7.4803 mL | |
| 10 mM | 0.3740 mL | 1.8701 mL | 3.7401 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
