General Description
2-nitrothiophen-3-amine is a chemical compound with the molecular formula C4H4N2O2S. It is a derivative of thiophene, a heterocyclic compound containing a sulfur atom in its five-membered ring. The presence of a nitro group and an amine group in the compound gives it potential applications in the production of pharmaceuticals, dyes, and agrochemicals. The nitro group is known for its reactivity and can be used as a precursor to synthesize various organic compounds. The amine group also makes it a versatile building block for organic synthesis. However, it is important to handle 2-nitrothiophen-3-amine with care, as nitro compounds are often explosive and toxic.
Check Digit Verification of cas no
The CAS Registry Mumber 52003-20-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,0,0 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 52003-20:
(7*5)+(6*2)+(5*0)+(4*0)+(3*3)+(2*2)+(1*0)=60
60 % 10 = 0
So 52003-20-0 is a valid CAS Registry Number.

A series of 4-(alkylamino)-1,2,4-triazoles transfer the alkylamino group to the 4-position of nitrobenzene and various 3-substituted nitrobenzenes, with no detectable ortho substitution.By contrast 2-nitrothiophene reacts in the 3-position and 2-nitronaphthalene in the 1-position; 1-nitronaphthalene gives a mixture of products derived from dominant 2- with some 4-substitution.The orientations are discussed and rationalized.
