Diisopropyl-phenyl-n-propyl-phosphonium, also known as DIPPP, is a phosphonium-based ionic liquid with the chemical formula C18H27NP. It is a colorless, viscous liquid that is widely used in various applications, including organic synthesis, catalysis, and as a solvent. DIPPP exhibits unique properties such as high thermal stability, low melting point, and excellent solvation capabilities. Its structure consists of two isopropyl groups, a phenyl group, and a n-propyl group attached to a central phosphonium cation, with a counterion typically being a halide or a non-coordinating anion. Due to its versatile nature, DIPPP has been employed in various chemical reactions, such as Friedel-Crafts alkylation, nucleophilic substitutions, and electrophilic aromatic substitutions, making it a valuable compound in the field of chemistry.
The CAS Registry Mumber 7333-80-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,3 and 3 respectively; the second part has 2 digits, 8 and 0 respectively. Calculate Digit Verification of CAS Registry Number 7333-80: (6*7)+(5*3)+(4*3)+(3*3)+(2*8)+(1*0)=94 94 % 10 = 4 So 7333-80-4 is a valid CAS Registry Number.
