General Description
4-(pyrazin-2-yl)thiazol-2-amine is a specialty chemical that belongs to the class of organic compounds known as thiazoles, characterized by a five-membered aromatic ring containing two nitrogen atoms and one sulfur atom. The scientific and technical properties of this chemical include its molecular formula C6H5N3S. It is also referred to by its systematic name which is 2-amino-4-(pyrazin-2-yl)thiazole. However, there is limited scientific or industrial data available about this chemical's specific chemical behavior, toxicity, usage in various applications, or physical properties such as melting point, boiling point, and solubility.
Check Digit Verification of cas no
The CAS Registry Mumber 19847-11-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,4 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19847-11:
(7*1)+(6*9)+(5*8)+(4*4)+(3*7)+(2*1)+(1*1)=141
141 % 10 = 1
So 19847-11-1 is a valid CAS Registry Number.

3,4-Substituted-5-aminopyrazoles and 4-substituted-2-aminothiazoles are frequently used intermediates in medicinal chemistry and drug discovery projects. We report an expedient flexible synthesis of 3,4-substituted-5-aminopyrazoles (35 examples), based on palladium-mediated α-arylation of β-ketonitriles with aryl bromides. A library of 4-substituted-2-aminothiazoles (21 examples) was assembled by a sequence employing Suzuki coupling of newly prepared, properly protected pinacol ester and MIDA ester of 4-boronic acid-2-aminothiazole with (hetero)aryl halides.
