Description
2-Naphthalenesulfonic acid sodium is the sodium salt of 2-naphthalenesulfonic acid, with empirical formula C₁₀H₇O₃SNa and CAS number 532-02-5. The compound has a molar mass of 230,22 g/mol. Naphthalenesulfonate salts are employed as intermediates in organic synthesis, as components in dye and surfactant chemistry, and in studies of aromatic sulfonic acid derivatives. The ionic sulfonate group confers water affinity that can be useful when formulating aqueous systems or preparing further functionalised naphthalene structures. This material is available from manufacturer Carl ROTH for research and process-development use. Accurate CAS and formula data on the pack support inventory control, safety documentation and method transfer between laboratories. Use standard precautions for solid organic sulfonates and store under conditions appropriate to laboratory chemicals of this class.

Questions about 2-Naphthalenesulfonic acid sodium, 500 g
What is this article?
2-Naphthalenesulfonic acid sodium, 500 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Metals, elements & oxides, inside Inorganic chemicals, in Lab chemicals.
Metals, elements and oxides are the element itself or its oxide, sold as powder, shot, foil or wire. Purity and particle size are both the specification. A 99 percent powder and a 99.999 percent shot of the same element are different articles. Many are reactive to air or to water.
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.
Which category should I open next?
