Salts and Inorganics
A variety of inorganic salts and elemental metals that can be used for large-scale, industrial purposes and everyday laboratory applications. Products are available in a range of chemical compositions, quantities, purities, and reagent grades.
Inorganics are elements and compounds, including carbon monoxide, carbon dioxide, carbonates, cyanides, cyanates, and carbides, that do not contain a carbon-hydrogen bond. This group also includes carbon allotropes such as graphite and graphene.
Because organic chemicals include only those that contain carbon atoms bonded to hydrogen atoms, the majority of elements in the periodic table and most substances in the material world are considered to be inorganic chemicals.
