Iodophthalein

Description:

Iodophthalein, with the CAS number 386-17-4, is a synthetic organic compound that belongs to the class of phthalein dyes. It is characterized by its bright yellow color and is primarily used as a pH indicator in various chemical applications. Iodophthalein exhibits a color change from yellow to pink as the pH of a solution transitions from acidic to alkaline conditions, making it useful in titrations and other analytical chemistry procedures. The compound is soluble in organic solvents but has limited solubility in water. Its molecular structure includes a phthalic acid derivative with iodine substituents, which contribute to its distinctive color properties. Iodophthalein is also noted for its stability under normal laboratory conditions, although it may degrade when exposed to strong acids or bases. Additionally, it has applications in biological staining and as a tracer in certain medical diagnostics. Safety precautions should be observed when handling this compound, as it may pose health risks if ingested or inhaled.

CAS: 386-17-4

3',3'',5',5''-Tetraiodophenolphthalein is a contrast agent used in diagnostic imaging, such as X-ray and CT scans. It is administered orally or intravenously and binds to the biliary ducts in the liver. This dye can also be used for diagnosis of inflammatory bowel disease by inducing an inflammatory response in the colon and rectum. 3',3'',5',5''-Tetraiodophenolphthalein is excreted through the kidneys, making it useful for detecting bladder and bowel diseases. The dye may also be used in phase chromatography to detect proteinuria, which is indicative of kidney disease. 3',3'',5',5''-Tetraiodophenolphthalein has been shown to have a negative effect on damaged tissue due to its strong oxidant properties.
