It is a derivative of benzo[d]isothiazol-3-one, featuring a 4-ethoxy-phenyl group attached to the 2-position. 2-(4-ethoxy-phenyl)-benzo[d]isothiazol-3-one is often used as a corrosion inhibitor in various industrial applications, particularly in the oil and gas industry, due to its ability to protect metal surfaces from corrosion. It is also known for its effectiveness in low concentrations and its compatibility with different types of metals. EPTB is a white to off-white crystalline solid that is soluble in organic solvents and has a relatively low toxicity profile, making it a preferred choice in many formulations.
The CAS Registry Mumber 2514-35-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,1 and 4 respectively; the second part has 2 digits, 3 and 5 respectively. Calculate Digit Verification of CAS Registry Number 2514-35: (6*2)+(5*5)+(4*1)+(3*4)+(2*3)+(1*5)=64 64 % 10 = 4 So 2514-35-4 is a valid CAS Registry Number.
