Biochemical Pathways
It is known to be involved in the synthesis of yttrium-based nanomaterials and organometallic yttrium complexes , which can have various downstream effects depending on their specific applications.
Pharmacokinetics
It has been documented that most of the yttrium administered was distributed into liver, bone, and spleen . Yttrium disappeared from the blood within 1 day but was retained in the organs for a long time . These findings suggest that Yttrium(III) chloride may have low bioavailability due to its rapid clearance from the blood and long retention in the organs.

生化学分析
Biochemical Properties
The biological effects of Yttrium refer to the activity, behavior, and toxicity of Yttrium element or compounds in cells, tissues, organs, and organisms . Yttrium is present in low abundance in soil, water bodies, and organisms . It is not an essential element for organisms and its bioavailability is very low .
Cellular Effects
Yttrium(III) chloride has been found to have acute hepatic injury and transient increase of plasma Ca following the injection . A significant and tremendous amount of Ca was deposited in the liver (over 10-fold) and spleen (over 100-fold), while Ca concentration was only slightly increased in the lung and kidney (less than 1.5-fold) . These results indicate that liver and spleen are primary target organs of intravenous-injected Yttrium(III) chloride .
Molecular Mechanism
Yttrium(III) chloride is taken up by phagocytic cells in the liver and spleen . Electron microscopic analyzes revealed that the colloidal yttrium-containing material was taken up by phagocytic cells in the liver and spleen .
Temporal Effects in Laboratory Settings
The elimination half-time of liver Y was 144 days at a dose of 1 mg Y/rat . Yttrium disappeared from the blood within 1 day but was retained in the organs for a long time .
Dosage Effects in Animal Models
The acute toxicity of Yttrium ion (Y3+), the deposition, retention, metabolism, and clearance have been documented in the previous reports . Hirano et al. studied time-course and dose-related changes in tissue distribution, subcellular localization, clearance, and acute toxicity of intravenous-injected Yttrium(III) chloride in rats .
Metabolic Pathways
Changes in Ca concentrations in liver, spleen, and lungs were in accordance with those of Yttrium(III) chloride . Two mechanisms of REE metabolism in the case of intravenous administration are suggested: (1) The REEs may be transported partly contained in serum protein and partly incorporated into phagocytes, and taken mostly into the reticuloendothelial system by the phagocytic mechanism and deposited there. (2) The major route of excretion of REEs may be biliary excretion and the REEs might be excreted gradually into feces .
Transport and Distribution
Yttrium(III) chloride is transported and distributed within cells and tissues . It is taken up by phagocytic cells in the liver and spleen .
Subcellular Localization
The subcellular localization of Yttrium(III) chloride is within the phagocytic cells in the liver and spleen . Electron microscopic analyzes revealed that the colloidal yttrium-containing material was taken up by phagocytic cells in the liver and spleen .
準備方法
Yttrium chloride is often prepared by the “ammonium chloride route,” starting from either yttrium oxide (Y₂O₃) or hydrated chloride or oxychloride . The synthetic route involves the following reactions:
From Y₂O₃: [ 10 \text{NH}_4\text{Cl} + \text{Y}_2\text{O}_3 \rightarrow 2 (\text{NH}_4)_2[\text{YCl}_5] + 6 \text{NH}_3 + 3 \text{H}_2\text{O} ]
From YCl₃·6H₂O: [ \text{YCl}_3·6\text{H}_2\text{O} + 2 \text{NH}_4\text{Cl} \rightarrow (\text{NH}_4)_2[\text{YCl}_5] + 6 \text{H}_2\text{O} ]
The pentachloride decomposes thermally to yield yttrium chloride(III): [ (\text{NH}_4)_2[\text{YCl}_5] \rightarrow 2 \text{NH}_4\text{Cl} + \text{YCl}_3 ]
