Description
SDS / sodium lauryl sulphate is a high-purity anionic surfactant supplied at min. 99 % for biochemistry, with empirical formula C₁₂H₂₅NaO₄S, CAS number 151-21-3 and molar mass 288,38 g/mol. The solid material exhibits a flash point of 170 °C and a boiling point of 216 °C, supporting controlled handling in molecular-biology and protein-chemistry settings. This biochemistry grade from manufacturer Carl ROTH is further identified by EG nr. 205-788-1 (UN number 1325). Sodium dodecyl sulphate remains a standard reagent for denaturing proteins, solubilising membranes and preparing SDS-PAGE samples, and the min. 99 % specification helps maintain reproducibility across batches. Research and diagnostic laboratories use it when a defined anionic detergent is required for extraction, purification support or analytical sample treatment. The combination of stated purity, molecular data and practical pack size makes this SDS a reliable choice for everyday biochemical applications.
This article belongs on Detergents & surfactants, in Biochemicals & reagents.

Questions about SDS / Sodium lauryl sulphate, min. 99 %, for biochemistry, 250 g, plastic
What is this article?
SDS / Sodium lauryl sulphate, min. 99 %, for biochemistry, 250 g, plastic 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.
