All reagents have a shelf life, whether they are liquids, powders, crystals, tablets, or test-strip pads.

If kept dry, powders and crystals are very stable; acids are also long lived. Date of manufacture is not the controlling factor when it comes to shelf life—storage conditions are more important.

Copper (II) sulfate has attracted many niche applications over the centuries. In industry copper sulfate has multiple applications. In printing it is an additive to book binding pastes and glues to protect paper from insect bites; in building it is used as an additive to concrete to provide water resistance and disinfectant qualities.

Clear, practical procedures for the preparation and application of these highly specific reagents are described indetail by leading copper Reagents: A Practical Approach is a comprehensive laboratory guide which will prove invaluable to all organic chemists wishing to use copper reagents in synthesis.

Copper-catalyzed 1,4-additions of organometallic reagents are robust C–C bond formation strategies applicable in a wide range of circumstances. This review analyses the syntheses of natural products and pharmaceutical agents, which rely on the application of asymmetric Cu-catalyzed conjugate additions of various organometallic reagents.
