Trimethidinium, also known as trimethyl-2,4,6-trimethylbenzenaminium, is a chemical compound with the molecular formula C10H16N. It is a colorless, crystalline solid that is soluble in water and has a molecular weight of 152.24 g/mol. Trimethidinium is primarily used as a cationic dye and is known for its ability to form complexes with various anions, such as iodide and chloride. It has been utilized in the textile industry for dyeing and printing, as well as in analytical chemistry for the detection and determination of certain anions. Due to its cationic nature, trimethidinium can also interact with negatively charged surfaces, making it a potential candidate for applications in materials science and surface modification.
The CAS Registry Mumber 7009-82-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,0 and 9 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 7009-82: (6*7)+(5*0)+(4*0)+(3*9)+(2*8)+(1*2)=87 87 % 10 = 7 So 7009-82-7 is a valid CAS Registry Number.
