Absorption, Distribution and Excretion
Following a single oral administration of 1 mg/kg body weight ((14)C-labeled test substance) to male rats (strain not specified), approximately 100% of the (14)C activity was absorbed via the digestive tract. Eight hours after a single intravenous injection of 1 mg/kg body weight ((14)C-labeled test substance) to male rats (strain not specified), approximately 50% of the radioactivity was detectable in the animal (excluding the gastrointestinal tract). Approximately 1.5% of the administered activity was detectable 3 days after administration, and after 6 days, the (14)C activity could not be measured further (limit of detection 0.3%). Approximately 0.1% of the (14)C activity was exhaled within 30 hours following a single oral or intravenous injection of 1 mg/kg body weight ((14)C-labeled test substance) to male rats (strain not specified). 1H-1,2,4-triazole (14)C-labeled substances were administered orally (dose: 1 mg/kg body weight) or intravenously (dose: 0.1, 1, 10, 100 mg/kg body weight) to male rats. Within 48 hours following a single administration, 92-94% of the (14)C-activity was excreted in the urine and 3-5% in the feces, regardless of whether the substance was administered orally or intravenously. For more complete data on the absorption, distribution, and excretion of 1H-1,2,4-triazoles (6 in total), please visit the HSDB records page. |

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).

| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 14.4781 mL | 72.3903 mL | 144.7807 mL | |
| 5 mM | 2.8956 mL | 14.4781 mL | 28.9561 mL | |
| 10 mM | 1.4478 mL | 7.2390 mL | 14.4781 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.
