Naphthalene-2-sulfonic acid 4-phenylbut-3-en-1-ylester, also known as 2-naphthol-6-sulfonic acid phenylallyl ester, is a complex organic compound with the chemical formula C18H16O4S. It is derived from naphthalene-2-sulfonic acid, which is a sulfonic acid derivative of naphthalene, and 4-phenylbut-3-en-1-yl, which is a phenyl-substituted allyl group. Naphthalin-2-sulfonsaeure-<4-phenyl-but-3-en-1-ylester> is characterized by its aromatic structure and the presence of a sulfonic acid group, which imparts water-soluble properties, and an ester linkage, which is formed between the sulfonic acid and the allyl group. It is typically used in chemical research and as an intermediate in the synthesis of various pharmaceuticals and dyes. The compound's structure and properties make it a versatile building block in organic synthesis, particularly in the preparation of compounds with potential applications in the fields of medicine and materials science.
The CAS Registry Mumber 7515-57-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,1 and 5 respectively; the second part has 2 digits, 5 and 7 respectively. Calculate Digit Verification of CAS Registry Number 7515-57: (6*7)+(5*5)+(4*1)+(3*5)+(2*5)+(1*7)=103 103 % 10 = 3 So 7515-57-3 is a valid CAS Registry Number.
