Copper formate tetrahydrate

Copper formate tetrahydrate [Cu(HCOO)2·4H2O], is a blue crystalline powder which is soluble in water. The formate ligand acts as organo-substitute for chlorides, sulfates, nitrates, fluorides, bromides, or nitrates. Cu(HCOO)2·4H2O has numerous uses both as a synthetic reagent in copper chemistry or as a copper source in many other applications. The Cu(HCOO)2·4H2O uses include, but are not limited to,
preserving pulp wood and ground pulp
mildew preventive,
preservative for cellulose materials
fungicidal agent,
preserving hides in leather tanning,
insecticidal agent
herbicidal agent
