Phosphonium, tributyl(3-methyl-2-butenyl)-, bromide is a complex organic compound with the chemical formula C14H30BrP. It is a phosphonium salt, which consists of a phosphonium cation (PH4+) and a bromide anion (Br-). The phosphonium cation is derived from tributyl(3-methyl-2-butenyl)phosphine, where three butyl groups (C4H9) are attached to a phosphorus atom, and a 3-methyl-2-butenyl group (C5H9) is bonded to the phosphorus as well. Phosphonium, tributyl(3-methyl-2-butenyl)-, bromide is used as a phase-transfer catalyst in various chemical reactions, particularly in the synthesis of pharmaceuticals and agrochemicals. It is known for its ability to facilitate reactions between organic and inorganic compounds by transferring them between different phases, such as from aqueous to organic solvents.
The CAS Registry Mumber 1530-50-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,3 and 0 respectively; the second part has 2 digits, 5 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1530-50: (6*1)+(5*5)+(4*3)+(3*0)+(2*5)+(1*0)=53 53 % 10 = 3 So 1530-50-3 is a valid CAS Registry Number.
