Applications
Zinc chloride is a widely used as a moderate-strength Lewis acid. In biochemistry research this is used for a source of the zinc ion. It is also be used alone or with phenols for preserving railway ties, fireproofing timber, and with ammonium chloride as a flux for soldering and etching of metals. Zinc chloride is used in the synthesis of the ferrocenylarenes. It is used for the in situ generation of organozincate reagents by reacting with Grignard compounds and also to catalyze chloromethylation of resins for solid phase peptide synthesis.
