Health Hazard
ACUTE/CHRONIC HAZARDS: When heated to decomposition 2-(4-Aminophenyl)-6-methyl-1,3-benzothiazole-7-sulfonic acid may emit very toxic fumes of SOx and NOx.
Fire Hazard
Flash point data for 2-(4-Aminophenyl)-6-methyl-1,3-benzothiazole-7-sulfonic acid are not available; however, 2-(4-Aminophenyl)-6-methyl-1,3-benzothiazole-7-sulfonic acid is probably combustible.

Poison by intravenous route. Seealso SULFONATES. When heated to decomposition itemits very toxic fumes of SOx and NO.
Check Digit Verification of cas no
The CAS Registry Mumber 130-17-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 130-17:
(5*1)+(4*3)+(3*0)+(2*1)+(1*7)=26
26 % 10 = 6
So 130-17-6 is a valid CAS Registry Number.

The present invention discloses a water-soluble benzothiazole dye synthesis method, which comprises: mixing p-toluidine, sodium sulfide and a catalyst, carrying out a cyclization reaction to produce 2-(4-anilino)-6-methyl-benzothiazole, carrying out a sulfonation reaction on the 2-(4-anilino)-6-methyl-benzothiazole and a sulfonation agent to produce 2-(4-anilino)-6-methyl-7-sulfonic-benzothiazole, adding the 2-(4-anilino)-6-methyl-7-sulfonic-benzothiazole (III) and a sodium hydroxide aqueous solution to a solvent, adding a carbonyl-containing compound, and carrying out a reaction to obtain the water-soluble benzothiazole dye. Compared with the synthesis method in the prior art, the synthesis method of the present invention has characteristics of cheap and readily available raw materials, simple process, safety and environmental protection, and is suitable for large-scale industrial production.
