149-45-1 Usage
Chemical Properties
light tan powder
Uses
Different sources of media describe the Uses of 149-45-1 differently. You can refer to the following data:
1. In determination of trace metals.
2. Tiron is a superoxide scavenger used in the study and examination of oxide electronics. Maintains the ability to remove or destroy magnetic moments which may occur on the surface of such materials.
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.

SULFONATION OF POLYHYDROXYAROMATICS
-
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.
