Ethyl acetimidate hydrochloride Chemical Properties,Usage,Production

Chemical Properties

white to light yellow crystal powder

Uses

Ethyl acetimidate hydrochloride was used in preparation of amidinated carbonic anhydrase via chemical modification of human erythrocyte carbonic anhydrase. It was also used in synthesis of methyl 2-methyl-2-thiazoline-4-carboxylate hydrochloride.

Purification Methods

Recrystallise the hydrochloride by dissolving it in the minimum volume of super dry EtOH and adding dry Et2O or from dry Et2O. Dry it in a vacuum and store it in a vacuum desiccator with P2O5. Alternatively it could be crystallised from EtOH (containing a couple of drops of ethanolic HCl) and adding dry Et2O. Filter and dry it in a vacuum desiccator over H2SO4 and NaOH.
