Aluminium is a defined chemical substance recorded by PubChem as Aluminum. Its molecular formula is Al, and its relative molecular mass is approximately 26.981538 g/mol. Aluminium(0) is an elemental aluminium. The precise salt, hydrate, stereochemical form, or derivative named in the row is retained because these distinctions can change composition, physicochemical behavior, dosing, and registry identity.
Its biological or pharmacological significance is governed by the specific molecular form and the interactions described above; dose, exposure route, formulation, and metabolism determine whether an observed effect is therapeutic, toxicological, or simply physicochemical. Major uses may include medicinal or biochemical research, analytical reference standards, impurity and stability testing, formulation studies, and regulated manufacturing where identity and purity are controlled.
