Thiamin (vitamin B1)
Thiamin was first isolated in 1926 from rice polishing by Jansen and Donath. Its empirical formula was established in 1931 by Windaus and co-workers and the chemical structure of the compound was elucidated in 1936 by Williams and co-workers.
The chemical name for this water soluble vitamin is 3-[(4-amino-2-methyl-5- pyrimidinyl) methyl] - 5-(2-hydroxyethy1)-4-methylthiazolium. Do not get perturbed by this long name. You would not be expected to remember this chemical name for thiamin.
