Methallyltributylphosphonium chloride (MTBP) is a quaternary phosphonium salt with the chemical formula C19H42ClP. It is a colorless, viscous liquid that is soluble in water and organic solvents. MTBP is widely used as a phase-transfer catalyst in various organic reactions, particularly in the synthesis of fine chemicals, pharmaceuticals, and agrochemicals. It is known for its ability to facilitate the transfer of reactants between immiscible phases, thereby enhancing reaction rates and selectivity. Additionally, MTBP has been studied for its potential applications in the extraction of metal ions and in the preparation of ionic liquids. Its stability, low toxicity, and ease of synthesis make it a valuable reagent in the field of organic chemistry.
The CAS Registry Mumber 1530-49-0 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, 4 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1530-49: (6*1)+(5*5)+(4*3)+(3*0)+(2*4)+(1*9)=60 60 % 10 = 0 So 1530-49-0 is a valid CAS Registry Number.
