Toxicity Summary
Identification and Uses: This chemical is a colorless, transparent crystal, white powder, or granules. Odorless; slightly soluble in water; insoluble in alcohol and ammonia. This chemical is used as a cleaning agent; in oil well drilling; water treatment; cheese emulsification; as a general chelating agent for rust removal; as a component of single-component ink removers; and for metal electrodeposition. It is also used in textile dyeing; wool washing; as a buffer; food additive; detergent auxiliaries; water softeners; and dispersants. Human Contact and Toxicity: Alkaline and irritating. Ingestion may cause nausea, vomiting, and diarrhea. Medical reports of acute exposure have shown mild to moderate skin and eye reactions. Animal Studies: High concentrations of tetrasodium pyrophosphate added to rat feed caused kidney damage. This chemical is teratogenic to chicken embryos. Acute studies have shown that direct exposure can cause severe eye irritation and corneal damage in rabbits and may be irritating to the skin. Ingestion of this chemical is considered moderately toxic and may induce metabolic acidosis and hypocalcemia. Interaction ……Sodium pyrophosphate can inhibit the deposition of calcium salts and the formation of calcifiable matrix in the aorta of rats treated with high doses of vitamin D. |

| Additional Infomation |
Tetrasodium pyrophosphate is an odorless white powder or granules. Melting point: 995 °C. Density: 2.53 g/cm³. Water solubility: 3.16 g/100 mL (cold water); 40.26 g/100 mL (boiling water). Used as a wool degreasing agent, bleaching agent, and food additive. Related substance: Tetrasodium pyrophosphate decahydrate (Na₄P₂O₇·10H₂O) is a colorless transparent crystal. It loses water when heated to 93.8 °C. Sodium pyrophosphate is an inorganic sodium salt composed of one phosphate (⁴⁻) anion and four sodium (¹⁺) cations. Its more common name is tetrasodium pyrophosphate, used as an emulsifier in the food industry and as a calcium chelating salt in oral hygiene. It can be used as a food emulsifier, chelating agent, and food thickener. It contains diphosphate (4-).

Mechanism of Action Arsenic herbicides are not growth regulators in the sense of plant hormones. They... inhibit plant growth through enzyme systems. They slowly kill plants; the initial symptoms are... yellowing leaves, cessation of growth, and gradual yellowing, then browning, and finally dehydration and death. /Organic Arsenic Herbicides/ |

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 | 3.7608 mL | 18.8041 mL | 37.6081 mL | |
| 5 mM | 0.7522 mL | 3.7608 mL | 7.5216 mL | |
| 10 mM | 0.3761 mL | 1.8804 mL | 3.7608 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.
