Di-n-butyl 4-iodophthalate is an organic compound with the chemical formula C16H19IO4. It is a derivative of phthalic acid, where two butyl groups are attached to the central benzene ring, and an iodine atom is present at the 4-position. di-n-butyl 4-iodophthalate is characterized by its pale yellow color and is soluble in organic solvents. It is primarily used as a plasticizer in the production of flexible polyvinyl chloride (PVC) materials, imparting flexibility and durability to the final product. Due to its chemical structure, di-n-butyl 4-iodophthalate can also be found in various industrial applications, such as adhesives, sealants, and coatings. However, it is important to note that the use of phthalates, including di-n-butyl 4-iodophthalate, has been a subject of concern due to potential health and environmental impacts, leading to regulations and restrictions in certain applications.
The CAS Registry Mumber 4842-04-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,4 and 2 respectively; the second part has 2 digits, 0 and 4 respectively. Calculate Digit Verification of CAS Registry Number 4842-04: (6*4)+(5*8)+(4*4)+(3*2)+(2*0)+(1*4)=90 90 % 10 = 0 So 4842-04-0 is a valid CAS Registry Number.
