Description
Lithium dodecyl sulphate (LDS) is an anionic surfactant of min. 99 % purity intended for biochemistry. It carries CAS number 2044-56-6, EG number 218-058-2 and the empirical formula C₁₂H₂₅LiO₄S, with a molar mass of 272,33 g/mol and a boiling point of 199 °C. LDS is widely employed as a lithium-based alternative to sodium dodecyl sulphate in protein solubilisation, electrophoretic sample preparation and membrane-protein work where sodium ions are undesirable. provides a practical bench quantity for buffer formulation, denaturing gels and detergent screens. Supplied for biochemistry from manufacturer Carl ROTH, the material fits routine laboratory workflows that demand a defined alkyl sulphate salt. Its strong detergent action supports disruption of hydrophobic interactions while remaining compatible with many downstream analytical steps. Laboratories working on proteomics, structural biology or formulation science can specify this grade by CAS, molar mass and stated purity. The compact unit size reduces waste when only small amounts are required for method optimisation or comparative surfactant studies.

Questions about Lithiumdodecyl sulphate (LDS), min. 99 %, for biochemistry, 10 g, plastic
What is this article?
Lithiumdodecyl sulphate (LDS), min. 99 %, for biochemistry, 10 g, plastic 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.
