58249-69-7 Usage
General Description
Benzothiazole, 5,6-dimethoxy- (9CI) is a chemical compound that belongs to the class of benzothiazoles, which are aromatic compounds containing a benzene ring fused to a thiazole ring. This particular compound has two methoxy groups attached at the 5 and 6 positions of the benzothiazole ring. It is commonly used as an intermediate in the synthesis of various organic compounds, including pharmaceuticals, dyes, and agrochemicals. Benzothiazole, 5,6-dimethoxy- (9CI) is also known for its potential biological activities, such as antimicrobial and antifungal properties. However, its specific uses and applications may vary depending on the industry and field of study.
Check Digit Verification of cas no
The CAS Registry Mumber 58249-69-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,2,4 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 58249-69:
(7*5)+(6*8)+(5*2)+(4*4)+(3*9)+(2*6)+(1*9)=157
157 % 10 = 7
So 58249-69-7 is a valid CAS Registry Number.

K2S as Sulfur Source and DMSO as Carbon Source for the Synthesis of 2-Unsubstituted Benzothiazoles

We describe a three-component reaction of o-iodoanilines with K2S and DMSO that provides 2-unsubstituted benzothiazoles in moderate to good isolated yields with good functional group tolerance. Electron-rich aromatic amines and o-phenylenediamines instead of o-iodoanilines provided 2-unsubstituted benzothiazoles and 2-unsubstituted benzimidazoles with and without K2S under similar conditions. Notably, DMSO plays three vital roles: carbon source, solvent, and oxidant.
