Atmofair 2-Naphthyl p-Toluenesulfonate (CAS 7385-85-5)

2-Naphthyl p-Toluenesulfonate (CAS 7385-85-5) has a molecular formula of C₁₇H₁₄O₃S and a molecular weight of 298.36 g/mol, consisting of a 2-naphthyl group esterified with p-toluenesulfonic acid (tosylic acid). As a tosylate ester, it acts as a versatile leaving group precursor in organic synthesis, commonly used for nucleophilic substitution reactions in pharmaceutical and fine chemical R&D. It requires sealed, cool, dry storage to prevent ester hydrolysis, ensuring high reactivity and stability for synthetic processes.
