Trisulfanediyldi-acetic acid, also known as 1,2,3-trisulfanediylbis(ethane-2,1-diyl) diacetate or TSDA, is a chelating agent with the chemical formula C6H10O8S3. It is a white crystalline solid that is soluble in water and has a molecular weight of 322.33 g/mol. TSDA is commonly used in various applications, such as a sequestering agent in detergents, a stabilizer in metalworking fluids, and a chelating agent in analytical chemistry. It forms stable complexes with metal ions, which helps prevent precipitation and corrosion. Due to its ability to bind with heavy metal ions, TSDA is also used in environmental remediation processes to remove toxic metals from contaminated water and soil.
The CAS Registry Mumber 16002-31-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,0,0 and 2 respectively; the second part has 2 digits, 3 and 1 respectively. Calculate Digit Verification of CAS Registry Number 16002-31: (7*1)+(6*6)+(5*0)+(4*0)+(3*2)+(2*3)+(1*1)=56 56 % 10 = 6 So 16002-31-6 is a valid CAS Registry Number.
