3,4,5,5-tetramethyl Δ2-pyrazoline is an organic compound with the molecular formula C?H??N?. It is a derivative of pyrazoline, a heterocyclic compound consisting of a pyrazole ring with an exocyclic double bond. The compound is characterized by the presence of four methyl groups (CH?) attached to the pyrazoline ring, with two methyl groups at the 3rd and 5th positions and two at the 4th and 5th positions. This structure contributes to its unique chemical properties and potential applications in various fields, such as pharmaceuticals and materials science. Due to its specific structure, 3,4,5,5-tetramethyl Δ2-pyrazoline may exhibit different reactivity and stability compared to other pyrazoline derivatives, making it an interesting subject for further research and development.
The CAS Registry Mumber 5519-43-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,1 and 9 respectively; the second part has 2 digits, 4 and 3 respectively. Calculate Digit Verification of CAS Registry Number 5519-43: (6*5)+(5*5)+(4*1)+(3*9)+(2*4)+(1*3)=97 97 % 10 = 7 So 5519-43-7 is a valid CAS Registry Number.
