2-Octyl-hydrochinon-5-sulfonsaeure, also known as 2-octylhydroquinone-5-sulfonic acid, is a chemical compound with the molecular formula C14H20O4S. It is a derivative of hydroquinone, featuring an octyl chain and a sulfonic acid group. This organic compound is primarily used as a stabilizer in the polymer industry, particularly for polyvinyl chloride (PVC). It helps to prevent the degradation of PVC caused by heat, light, and oxygen, thereby extending the material's lifespan and maintaining its physical properties. The compound's octyl chain provides steric hindrance, which can enhance its stability and effectiveness in various applications.
The CAS Registry Mumber 895-21-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,9 and 5 respectively; the second part has 2 digits, 2 and 1 respectively. Calculate Digit Verification of CAS Registry Number 895-21: (5*8)+(4*9)+(3*5)+(2*2)+(1*1)=96 96 % 10 = 6 So 895-21-6 is a valid CAS Registry Number.
