Description
Sodium dodecylbenzenesulfonate is an anionic surfactant mixture for laboratory and biochemical use, identified by CAS number 25155-30-0 and the empirical formula C₁₈H₂₉NaO₃S. With a molar mass of 348,48 g/mol, this alkylbenzenesulfonate salt supports workflows that rely on controlled surface-active behaviour, including solubilisation, dispersion, and detergent-based sample handling. Its amphiphilic character makes it relevant for protein work, micellar systems, and analytical protocols where hydrophobic components must be brought into solution. Offered by manufacturer Carl ROTH within the biochemicals range, the product provides a clearly defined molecular identity in mixture form for consistent day-to-day laboratory use. Research and quality-control environments can integrate this grade into established methods for cleaning formulations, extraction steps, or general surface-tension modification without unnecessary reformulation. balances bench convenience with sufficient stock for ongoing campaigns and method development.
This article belongs on Detergents & surfactants, in Biochemicals & reagents.

Questions about Sodium dodecylbenzenesulfonate, mixture, 500 g
What is this article?
Sodium dodecylbenzenesulfonate, mixture, 500 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Detergents & surfactants, inside Biochemicals & reagents, in Life Science & Microbiology.
A laboratory detergent or surfactant, such as SDS, Tween or Triton, solubilises membranes and stops proteins sticking. The average chain length and the peroxide content matter, especially for a protein that a peroxide would damage. A cleaning detergent for glassware is a different product.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
