:Chromotropic acid disodium salt dihydrate
Description:
Chromotropic acid disodium salt dihydrate, with the CAS number 5808-22-0, is a chemical compound that serves primarily as a reagent in analytical chemistry, particularly in the detection of aluminum ions. It is characterized by its bright orange-red color, which is attributed to the chromotropic acid structure. The compound is a disodium salt, indicating that it contains two sodium ions per molecule, and it exists in a dihydrate form, meaning it incorporates two water molecules in its crystalline structure. This compound is soluble in water, making it useful in various aqueous applications. Chromotropic acid disodium salt dihydrate exhibits strong chelating properties, allowing it to form stable complexes with metal ions, which is essential for its role in colorimetric assays. Additionally, it is relatively stable under standard laboratory conditions but should be handled with care, as with all chemical reagents, to avoid any potential hazards. Its applications extend beyond analytical chemistry to include uses in biological and environmental studies, where it aids in the detection and quantification of specific metal ions.

CAS:<p>Chromotropic acid dihydrate is a chromogenic compound that has an adsorption mechanism and is used as an analytical reagent. Chromotropic acid disodium dihydrate (CDA) is used in the determination of hydrochloric acid, natural gas and other liquids. It also can be used to measure the concentration of tyramine hydrochloride. CDA has been shown to be effective in the measurement of molecular orbitals and kinetic constants. The optical sensor is sensitive to wavelengths ranging from 200-900 nm, with a peak absorption at around 500 nm. This sensor can be used for many types of chemical reactions, such as organic synthesis, hydrogenation, and oxidation.</p>Formula:C10H6O8S2Na2·2H2OPurity:Min. 95%Color and Shape:Off-White PowderMolecular weight:400.29 g/molChromotropic acid disodium salt dihydrate - ACS reagent
CAS:<p>Chromotropic acid is a reactive compound that has been shown to be adsorbed on the surface of activated carbon. The adsorption mechanism and the kinetic constants for this reaction have been studied in detail. Chromotropic acid decomposes at high temperatures, releasing hydrogen chloride gas and water vapor. This chemical is also used in pharmaceutical preparations as an additive to inhibit oxidation reactions. It may also serve as a photoreceptor, reacting with tyramine hydrochloride and other compounds to produce a color change.</p>Formula:C10H6O8S2Na2·2H2OColor and Shape:PowderMolecular weight:400.29 g/molChromotropic Acid Disodium Salt Dihydrate extrapure AR, ACS, ExiPlus, Multi-Compendial, 99%
