Trimethyl-4-(6-methylpyrimidinyl)ammoniumchlorid, also known as TMMPA, is a quaternary ammonium compound with the chemical formula C9H16ClN3. It is a white crystalline solid that is soluble in water and organic solvents. TMMPA is widely used as a phase transfer catalyst in various organic reactions, particularly in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals. It facilitates the transfer of reactants between immiscible phases, thereby enhancing reaction rates and selectivity. Additionally, TMMPA exhibits antimicrobial properties and can be used as a preservative in various applications. Its stability, low toxicity, and ease of synthesis make it a popular choice in the chemical industry.
The CAS Registry Mumber 51957-34-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,9,5 and 7 respectively; the second part has 2 digits, 3 and 4 respectively. Calculate Digit Verification of CAS Registry Number 51957-34: (7*5)+(6*1)+(5*9)+(4*5)+(3*7)+(2*3)+(1*4)=137 137 % 10 = 7 So 51957-34-7 is a valid CAS Registry Number.
