Calcium lactobionate

Calcium lactobionate (CAS 5001-51-4) is the calcium salt of lactobionic acid, also referenced as NSC 15850 and calcium lactobionate hydrate. It carries no assigned E-code and is classified under HS code 2940.00.6000. It is commercially available as a white crystalline powder with high water solubility.

In pharmaceutical formulations, calcium lactobionate serves as a bioavailable calcium source in intravenous and oral preparations, where its chelating capacity stabilises active compounds against oxidative degradation. In food and nutrition applications, it functions as a sequestrant that binds divalent metal ions, slowing lipid oxidation and extending shelf life in dairy and processed food systems.

Calcium lactobionate is supplied in pharmaceutical and food-grade forms meeting Ph.Eur. and FCC specifications, and is registered under REACH for supply within the European Economic Area. Standard packaging formats include multi-layer bags and fibre drums sized for laboratory and industrial-scale procurement.
