Ethyl-methyl-diphenyl-phosphonium bromide (EMPB) is a phosphonium salt with the chemical formula C15H18BrP. It is a colorless, crystalline solid that is soluble in water and organic solvents. EMPB is a versatile reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the Wittig reaction, where it acts as a source of the ylid. The ylid generated from EMPB can be used to alkylate aldehydes and ketones, leading to the formation of olefins. Additionally, EMPB has applications in the synthesis of various phosphorus-containing compounds and as a catalyst in certain chemical transformations. Its stability, ease of preparation, and reactivity make it a valuable tool in the field of organic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 2129-86-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,2 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2129-86:
(6*2)+(5*1)+(4*2)+(3*9)+(2*8)+(1*6)=74
74 % 10 = 4
So 2129-86-4 is a valid CAS Registry Number.
