Sodium glucoheptonate (H-Quest A300)

​Sodium Glucoheptonate (H-Quest A300), is natural chelating agent, formed through the synthesis of sodium cyanide and high purity sugar to produce light-tan crystals of the α isomer, after crystallisation. They are an inherently biodegradable replacement for traditional chelate such as NTA and EDTA and exhibit excellent natural sequestration power over a broad range of di- and tri-valent metal ions, (Ca2+, Mg2+, Fe2+, Fe3+, Zn2+, Al3+). H-Quest A300 is highly compatible with strong alkali solutions (pH 8.00-10.00), which can prevent the bacterial and fungal degradation of the solution. Unlike EDTA and NTA chelating agents, H-Quest A300 is a non-toxic, non-hazardous, non-corrosive product and therefore a much safer compound.
