Description
Dioctahedral smectite is a layered aluminosilicate material supplied at a minimum content of 50 % for chemical and biochemical laboratory applications. It is characterised by the empirical formula Al₂O₉Si₃, a molar mass of 282,21 g/mol, and CAS number 1318-93-0, enabling unambiguous identification in purchasing and experimental records. The product is Smectite-type clays are widely employed in research settings that study adsorption, swelling behaviour, ion exchange, or solid-supported processes, and a clearly specified dioctahedral grade helps align material choice with experimental design. This grade is available from manufacturer Carl ROTH as part of its chemicals and biochemicals offering. Documented molar mass and CAS data facilitate inventory control, safety assessment, and comparison across batches. Laboratories seeking a defined dioctahedral smectite for exploratory or routine work can rely on the stated minimum assay and pack format without additional unspecified performance claims.

Questions about Dioctahedral smectite, min. 50 %, 1 kg
What is this article?
Dioctahedral smectite, min. 50 %, 1 kg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
