Thieno[2,3-d]pyridazine is a heterocyclic compound characterized by a fused ring structure consisting of a thiophene and a pyridazine. Thiophene is a five-membered aromatic ring with one sulfur atom, while pyridazine is a six-membered aromatic ring with two nitrogen atoms. The fusion of these two rings at positions 2 and 3 of the pyridazine creates a unique chemical structure with potential applications in various fields, such as pharmaceuticals and materials science. Thieno[2,3-d]pyridazine is known for its diverse chemical properties and reactivity, which can be further modified through substitution or functionalization at different positions on the ring. The specific properties and applications of thieno[2,3-d]pyridazine derivatives depend on the substituents and the context in which they are used.

272-15-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 272-15-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,7 and 2 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 272-15:
(5*2)+(4*7)+(3*2)+(2*1)+(1*5)=51
51 % 10 = 1
So 272-15-1 is a valid CAS Registry Number.

Reaction of anhydrous zinc chloride with 2,3-thiophenedicarbaldehyde bis(semicarbazone) (2,3BSTCH2) and bis(thiosemicarbazone) (2,3BTSTCH2): Crystal structure of {[C6H5N2S]+[ZnCl3(C6H4N2S)]-} complex

Alomar, Kusa?,Allain, Magali,Richomme, Pascal,Bouet, Gilles

, p. 1591 - 1597 (2015/10/20)

The reaction of anhydrous zinc chloride with 2,3-thiophenedicarbaldehyde bis(semicarbazone) or 2,3-bis(thiosemicarbazone) leads to the formation of compound {[C6H5N2S]+[ZnCl3(C6H4N2S)]-}, where C6H4N2S is thieno[2,3-d]pyridazine, via an elimination-cyclisation reaction of the semicarbazone or the thiosemicarbazone moiety. Crystal structures of thieno[2,3-d]pyridazine and {[C6H5N2S]+[ZnCl3(C6H4N2S)]-} are described. 2015 Institute of Chemistry, Slovak Academy of Sciences
