Description and Uses
Acetanilide is used as an intermediate in the synthesis of rubber accelerator, dyes and camphor. It is also used in the synthesis of penicillin and other pharmaceutical products. It is involved in the preparation of 4-acetamidobenzenesulfonyl chloride, which is an intermediate during the synthesis of sulfa drugs. Further, it is employed as a experimental photographic developer. In addition to this, it is used to stabilize cellulose ester varnishes.
