CAS 90049-81-3

Benzo[b]thiophene, 5-nitro-, 1,1-dioxide, identified by CAS number 90049-81-3, is a heterocyclic organic compound that features a fused benzene and thiophene ring system with a nitro group and a sulfone functional group. This compound typically exhibits a pale yellow to brown solid appearance and is characterized by its aromatic nature, which contributes to its stability and potential reactivity. The presence of the nitro group introduces electron-withdrawing characteristics, influencing its chemical behavior and reactivity in various reactions, such as electrophilic substitution. The 1,1-dioxide functional group indicates the presence of two oxygen atoms bonded to the sulfur atom, enhancing its solubility in polar solvents. This compound may be of interest in organic synthesis and materials science due to its unique structural features and potential applications in pharmaceuticals or agrochemicals. However, specific safety and handling guidelines should be followed, as with all chemical substances, to mitigate any associated risks.
