Uses
Different sources of media describe the Uses of 4628-94-8 differently. You can refer to the following data:
1. thiadiazole pharmaceutical intermediate
2. 1,3,4-thiadiazole-2,5-dithiol (Bismuthiol I) was used in determination of tellurium in indium phosphide doped with cadmium telluride by electro thermal atomic absorption spectrometry. It forms polymers with metals and can be useful in treatment of metal-polluted water.
General Description
1,3,4-thiadiazole-2,5-dithiol undergoes copolymerization with 1+, 2+ and 3+ valent metals to form coordination polymers. It forms polymers with metals and can be useful in treatment of metal-polluted water.
Purification Methods
Usually contaminated with disulfide. Purify it by recrystallisation from EtOH. It is a reagent for the detection of Bi, Cu, Pb and Sb. [Najumdar & Chacraborty Anal Chim Acta 19 372 1958, Fries Z Anal Chem 165 100, 1959, Beilstein 27 IV 7725.]
Check Digit Verification of cas no
The CAS Registry Mumber 4628-94-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,2 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4628-94:
(6*4)+(5*6)+(4*2)+(3*8)+(2*9)+(1*4)=108
108 % 10 = 8
So 4628-94-8 is a valid CAS Registry Number.
