Description
Disodium 2-naphthol-3,6-disulfonate is a sulfonated naphthol salt for laboratory and process chemistry applications. It is identified by CAS number 135-51-3, empirical formula C₁₀H₆Na₂O₇S₂ and a molar mass of 348,26 g/mol, corresponding to the disodium salt of 2-naphthol bearing sulfonate groups at the 3- and 6-positions. This ionic aromatic structure is relevant where water-compatible naphthol derivatives, dye intermediates or sulfonated coupling components are required in chemical and biochemical workflows. The product is Molecular mass and formula data support accurate preparation of solutions and stoichiometric calculations. Positioned in the chemicals and biochemicals offering from manufacturer Carl ROTH, the salt serves laboratories that need a defined disulfonated naphthol reagent without additional grade claims beyond the manufacturer description. Use standard laboratory practice for sulfonated organics, consult the safety documentation before handling, and integrate the stated molar mass into your weighing and dilution protocols.

Questions about Disodium 2-naphthol-3,6-disulfonate, 500 g
What is this article?
Disodium 2-naphthol-3,6-disulfonate, 500 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Inorganic salts, inside Inorganic chemicals, in Lab chemicals.
An inorganic salt is an ionic solid, a chloride, a sulfate, a nitrate, a phosphate. The degree of hydration changes the mass that contains one mole of the ion. Analytical grade limits the foreign ions. A hydrate and the anhydrous salt are not interchangeable by weight.
An inorganic chemical is a salt, an acid or base in solid form, a metal, an oxide, or an element. The waters of hydration are part of the formula: a hydrate and an anhydrous salt are different masses for the same ion. Trace metals matter when the salt will be used in analysis. Nanomaterials add particle size to the specification. Look the substance up on PubChem. Hazard classes are on ECHA, under the CLP Regulation and REACH. Transport of the dangerous ones is explained by the UNECE.
