(2,2-diphenyl-2-hydroxyethyl)trimethylammonium bromide, also known as DPTA, is a quaternary ammonium compound with the chemical formula C21H26BrNO. It is a white crystalline solid that is soluble in water and organic solvents. DPTA 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, antimicrobial agent, and in the preparation of various pharmaceuticals and agrochemicals. Due to its cationic nature, DPTA can interact with negatively charged surfaces, making it useful in applications such as water treatment and textile processing. Its chemical structure consists of a central nitrogen atom bonded to three methyl groups and a 2-hydroxyethyl group, which is further connected to two phenyl rings. The bromide ion is the counterion in this salt form of the compound.

1879-50-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1879-50-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,7 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.Calculate Digit Verification of CAS Registry Number 1879-50:
(6*1)+(5*8)+(4*7)+(3*9)+(2*5)+(1*0)=111
111 % 10 = 1
So 1879-50-1 is a valid CAS Registry Number.
