It is a quaternary phosphonium salt that is commonly used as a phase-transfer catalyst in organic synthesis. It is a white or off-white solid that is insoluble in water but soluble in organic solvents. (3-BROMOBUTYL)TRIPHENYLPHOSPHONIUM BROMIDE is known for its ability to facilitate various reactions such as nucleophilic substitution, alkylation, and deprotonation by transferring a charged species from one phase to another. It is considered to be a versatile and efficient catalyst in organic chemistry and has applications in various synthetic processes.
Check Digit Verification of cas no
The CAS Registry Mumber 132256-97-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,2,5 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132256-97:
(8*1)+(7*3)+(6*2)+(5*2)+(4*5)+(3*6)+(2*9)+(1*7)=114
114 % 10 = 4
So 132256-97-4 is a valid CAS Registry Number.

HIGHLY REACTIVE EQUIVALENTS OF ALLYLIDENETRIPHENYLPHOSPHORANES FOR THE STEREOSPECIFIC SYNTHESIS OF 1,3-DIENES BY CIS-OLEFINATION OF HINDERED ALDEHYDES
Corey, E. J.,Desai, Manoj C.
, p. 5747 - 5748 (1985)
Ylides derived from 3-dimethylaminopropyltriphenylphosphonium salts react smoothly and stereospecifically with even hindered aldehydes to form Z-olefins which are easily converted to 1,3-dienes.
