Chemical Product Description & Applications

(S)-3-[1-(Dimethylamino)ethyl]phenol is a chiral phenolic precursor to rivastigmine and corresponds to its decarbamylated structural fragment. It provides the required S-configured aminoethyl side chain and a phenolic hydroxyl that can be converted into the ethylmethylcarbamate group. These features make it relevant both to synthetic assembly and to analysis of rivastigmine-related material.

The selected form is the free compound, not the hydrochloride and not the R enantiomer. Its unprotected phenol allows direct access to oxygen functionalization, while the tertiary amine remains part of the final molecular skeleton. The same identity is associated with rivastigmine-related compound analysis, but a synthesis-grade lot should not be described as a certified analytical standard without the appropriate characterization.

Typical Applications

  • Rivastigmine synthesis: Used as the S-configured phenol in carbamoylation routes that construct the drug’s aryl carbamate, retaining the existing dimethylaminoethyl stereocenter.
  • Related-compound analytical studies: Used as an identified decarbamylated comparator during development of chromatographic methods for rivastigmine, helping distinguish the phenolic precursor from the intact carbamate.
