SDS of cas: 67-51-6. I found the field of Chemistry very interesting. Saw the article Synthesis and Cyclizations of N-(Thieno[2,3-b]pyridin-3-yl)cyanoacetamides published in 2019.0, Reprint Addresses Dotsenko, VV (corresponding author), Kuban State Univ, Krasnodar, Russia.; Dotsenko, VV (corresponding author), North Caucasian Fed Univ, Stavropol, Russia.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole.

3-Aminothieno[2,3-b]pyridine-2-carboxylic acid esters readily reacted with 3,5-dimethyl-1-(cyanoacetyl)-1H-pyrazole to give previously unknown N-(thieno[2,3-b]pyridin-3-yl)cyanoacetamides. Reactions of the latter with 2-(arylmethylidene)malononitriles were nonselective, and mixtures of different heterocyclization products were generally formed. The cyclization of ethyl 4,6-dimethyl-3-[(cyanoacetyl)amino]thieno[2,3-b]pyridine-2-carboxylate afforded 2,4-dihydroxy-7,9-dimethylthieno[2,3-b : 4,5-b’]dipyridine-3-carbonitrile whose tautomeric equilibrium was studied by DFT quantum chemical calculations. In silico analysis of biological activity of the synthesized compounds was performed.
