text: Its production was first described by Basil Valentine in Currus Triumphalis Antimonii. In 1659, Johann Rudolf Glauber gave a relatively exact chemical interpretation of the reaction.
  Vittorio Algarotti introduced the substance into medicine, and derivatives of his name (algarot, algoroth) were associated with this compound for many years.
  The exact composition was unknown for a very long time. The suggestion of SbOCl being a mixture of antimony trichloride and antimony oxide or pure SbOCl were raised. Today the hydrolysis of antimony trichloride is understood; first the SbOCl oxychloride is formed which later forms SbOCl.
