2.4-(CH3)2C5H3N*BH3, also known as 2,4-dimethyl-6-aminopyridine borane complex, is a chemical compound that combines a 2,4-dimethyl-6-aminopyridine molecule with a borane molecule. This complex is widely used as a reducing agent in organic synthesis, particularly for the reduction of carbonyl compounds to alcohols. The borane moiety provides the reducing power, while the pyridine acts as a Lewis base, stabilizing the intermediates and facilitating the reaction. The 2,4-dimethyl groups on the pyridine ring enhance the electron-donating ability of the nitrogen, making the complex more effective as a reducing agent. 2.4-(CH3)2C5H3N*BH3 is also known for its stability and ease of handling, which makes it a popular choice in laboratory settings for various reduction reactions.
The CAS Registry Mumber 3999-41-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,9 and 9 respectively; the second part has 2 digits, 4 and 1 respectively. Calculate Digit Verification of CAS Registry Number 3999-41: (6*3)+(5*9)+(4*9)+(3*9)+(2*4)+(1*1)=135 135 % 10 = 5 So 3999-41-5 is a valid CAS Registry Number.
