Descripción

Descripción general

Calcium chloride dihydrate is a moisture resistant, cheap and commonly available calcium salt. Its efficacy as a chiral catalyst for various asymmetric organic reactions has been evaluated.

Aplicación

Calcium chloride dihydrate may be used in combination with sodium borohydride for the asymmetric reduction of 1-(2,2-dimethyl-4H-1,3-benzodioxin-6-yl)-2-[(1S)-2-hydroxy-1-phenylethylamino]ethanone to form (1R)-1-(2,2-dimethyl-4H-1,3-benzodioxin-6-yl)-2-[(1S)-2-hydroxy-1-phenylethylamino]ethanol.

Calcium chloride dihydrate has been used as a calcium supplement for the DMEM (Dulbecco′s modified Eagle′s medium) for use in cell culture studies. It has also been used to prepare the synthetic brine solution.
It may be used in the preparation of calcium-alginate beads.
