Benzenepentanaminium, N,N,N-trimethyl-, bromide, also known as 5-(N,N,N-trimethylammonio)pentylbenzene bromide or TMAP-Br, is a quaternary ammonium salt with the chemical formula C11H22BrN. It is a colorless, crystalline solid that is soluble in water and organic solvents. TMAP-Br is widely used as a phase-transfer catalyst in organic synthesis, facilitating the transfer of reactants between aqueous and organic phases. It is also employed as a surfactant and a reagent in various chemical processes. Due to its cationic nature, TMAP-Br exhibits antimicrobial properties and is used in some applications as a biocide. The compound is generally stable, but it should be stored away from heat and moisture to prevent decomposition.
The CAS Registry Mumber 7322-12-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,2 and 2 respectively; the second part has 2 digits, 1 and 2 respectively. Calculate Digit Verification of CAS Registry Number 7322-12: (6*7)+(5*3)+(4*2)+(3*2)+(2*1)+(1*2)=75 75 % 10 = 5 So 7322-12-5 is a valid CAS Registry Number.
