Absorption, Distribution and Excretion
Following intravenous injection, iodobenzoic acid is primarily distributed in the extracellular fluid. The plasma concentration of radioactive contrast agents such as iodobenzoic acid varies with dose and injection rate. Approximately 80% of the administered dose remains extravascular within 5 minutes of administration. However, there are exceptions, such as in the brain, nerve tissue, and testes, where tight junctions prevent drug diffusion outside the blood vessels. Following intravenous injection, iodobenzoic acid is primarily excreted unchanged via the kidneys. Its clearance pathways include glomerular filtration and tubular reabsorption of water. Approximately 83% of the administered dose is excreted 3 hours after administration, and approximately 100% after 24 hours. Metabolism/Metabolites Most of the administered dose of acetoiodic acid remains unchanged. Biological Half-Life It has been reported that the half-life of water-soluble contrast agents (such as acetoiodic acid) is approximately 4 hours. |

Protein Binding
Radioactive contrast agents such as acetoiodic acid exist in plasma in free form, with less than 5% of the injected dose being bound to proteins. |

| Additional Infomation |
Acetyliodic acid is an aminobenzoic acid. The molecular formula of acetyliodic acid is 3-acetaminophen-2,4,6-triiodobenzoic acid. It was the first monomeric ionic compound used as an X-ray contrast agent. It was first synthesized by Wallingford in 1953, and an application was submitted to the U.S. Food and Drug Administration (FDA) on February 8, 1978, by Cilag Chemie AG, a subsidiary of Johnson & Johnson. In FDA records, acetyliodic acid is listed as an inactive drug. It is an iodinated radiocontrast agent used in hysterosalpingography (HSG) in the form of sodium acetyliodate. The indication for acetyliodic acid is its use as an X-ray contrast agent. Some data suggest that its renal affinity is a characteristic of its application. X-ray imaging relies on differences in tissue density caused by X-ray attenuation between the target area and surrounding tissues. The use of contrast agents can enhance contrast or render images non-visible, thereby improving the ability to distinguish pathological processes from normal tissues.
Mechanism of Action Iodine is the main component of acetoiodic acid, an element with a very high atomic density. This property causes attenuation of X-rays within the diagnostic energy range. Therefore, acetoiodic acid is a water-soluble and relatively safe iodinated contrast agent that can be used clinically via intravenous injection. |

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).

*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.
