149-45-1 Usage
Description
Tiron, also known as sodium 4,5-dihydroxy-1,3-benzenedisulfonate, is a light tan powder with unique chemical properties. It is a versatile compound that has found applications in various fields due to its ability to act as a superoxide scavenger and its involvement in the determination of trace metals.
Uses
Used in Trace Metal Determination:
Tiron is used as a reagent in the determination of trace metals. Its chemical properties allow it to interact with metal ions, making it a valuable tool in analytical chemistry for detecting and quantifying trace amounts of metals in various samples.
Used in Oxide Electronics:
Tiron is used as a superoxide scavenger in the study and examination of oxide electronics. It plays a crucial role in maintaining the integrity of these materials by removing or destroying magnetic moments that may occur on the surface of oxide electronics, ensuring their proper functioning and performance.
Purification Methods
Recrystallise it from water [Hamaguchi et al. Anal Chim Acta 9 563 1962]. Itisan indicator colour reagent for Fe, Mn, Ti and Mo ions and complexes with Al, Cd, Co, Co, Fe (III), Mn, Pd, UO22+, VO2+ and Zn. [Beilstein 11 IV 630.]
Check Digit Verification of cas no
The CAS Registry Mumber 149-45-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,4 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 149-45:
(5*1)+(4*4)+(3*9)+(2*4)+(1*5)=61
61 % 10 = 1
So 149-45-1 is a valid CAS Registry Number.

Page/Page column 8, (2011/04/13)
The present invention provides improved process for the sulfonation of hydroxyaromatics amenable to direct isolation of the sulfonylated hydroxyaromatics in their free-acid forms. The process allows for the recyclization of sulfuric acid and minimizes waste. The starting materials are from a renewal resource, e.g., biomass, and contain detectable 14C up to a 14C content of 0.0000000001% (one part per trillion). The products made include sulfonated catechol, disulfonated pyrogallol and sulfonated protocatechuic acid.
