12262-49-6 Usage
Description
Solvent Blue 8 is a synthetic dye that is derived from green ash and is characterized by its solubility in water and slightly in ethanol, resulting in a blue color. It also exhibits different color shades when mixed with concentrated sulfuric acid (yellow-green) and upon dilution (blue). When mixed with a dye aqueous solution and sodium hydroxide, it produces a purple color with a dark purple precipitation.
Uses
Used in Textile Industry:
Solvent Blue 8 is used as a dye for coloring fabrics in the textile industry. Its ability to produce a range of blue shades makes it a versatile choice for various textile applications.
Used in Plastics and Polymers Industry:
Solvent Blue 8 is used as a colorant for plastics and polymers, providing a vibrant blue color to these materials. Its heat-resistant properties make it suitable for use in various plastic products that may be exposed to high temperatures during processing or use.
Used in Inks and Paints Industry:
Solvent Blue 8 is used as a pigment in the production of inks and paints, offering a stable blue color that is resistant to fading when exposed to light and heat. Its poor light fastness and heat resistance make it less suitable for applications requiring high durability, but it can still be used in certain formulations where these properties are not critical.
Used in Analytical Chemistry:
Solvent Blue 8 can be used as an indicator in analytical chemistry due to its color-changing properties when mixed with different chemicals, such as sodium carbonate and hydrochloric acid. This makes it useful for detecting the presence of specific ions or pH changes in a solution.
Preparation
N1,N1-dimethylbenzene-1,4-diamine in Sodium thiosulfate (had better have with Aluminium sulfate) exist, the Dichromate treatment into sulfur generation sulfonic acid (2 – amino – 5 – dimethylaminobenzene thiosulfate), this product then through Dichromate and N,N-dimethylaniline processing, Into indamine – thio acid, then use Dichromate and Copper sulfate monohydrate (or MnO2) cyclization and oxidation, and finally to Zinc chloride double salt out (2C116H18N3SC1,ZnC1.H2O).

Check Digit Verification of cas no
The CAS Registry Mumber 12262-49-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,6 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 12262-49:
(7*1)+(6*2)+(5*2)+(4*6)+(3*2)+(2*4)+(1*9)=76
76 % 10 = 6
So 12262-49-6 is a valid CAS Registry Number.

Amyloid-β (Aβ) aggregates are one of biomarkers of Alzheimer's disease (AD). It is well known that Aβ aggregates display neurotoxicty or cytotoxicity to neurons. Thus, degrading Aβ aggregates is crucial for exploring the treatment of AD. Moreover, the excessive production of HOCl in the AD brain is an important feature of the disease. Herein, a novel compound MB-O based on methylene blue (MB) skeleton was designed and synthesized. The probe MB-O can specifically react with HOCl, releasing the fluorophore MB with strong fluorescence intensity increase. More importantly, the released MB is capable of degrading Aβ aggregates under red light irradiation.
