4'-(1-Hydroxy-butyl)-m-terphenyl is an organic compound with the molecular formula C18H22O. It is a derivative of m-terphenyl, which is a type of terphenyl, a class of organic compounds consisting of three phenyl rings connected in a row. The compound is characterized by the presence of a hydroxybutyl group (a butyl chain with a hydroxyl group) attached to the 4' position of the central phenyl ring in the m-terphenyl structure. This chemical is primarily used as a UV stabilizer and light stabilizer in the plastics industry, particularly for polyolefins, to protect them from degradation caused by exposure to ultraviolet radiation. It helps maintain the color, strength, and flexibility of the material, thereby extending its lifespan and performance.
The CAS Registry Mumber 5195-14-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,9 and 5 respectively; the second part has 2 digits, 1 and 4 respectively. Calculate Digit Verification of CAS Registry Number 5195-14: (6*5)+(5*1)+(4*9)+(3*5)+(2*1)+(1*4)=92 92 % 10 = 2 So 5195-14-2 is a valid CAS Registry Number.
