Description
Direct Orange 26 is a technical-grade azo dye intermediate supplied for laboratory and technical chemistry use. It is specified with CAS number 3626-36-6, empirical formula C₃₃H₂₂N₆Na₂O₉S₂ and a molar mass of 756,67 g/mol, reflecting a disodium sulfonated bis-azo structure typical of direct orange colorants. The technical grade designation indicates suitability for applications where a defined dye identity is required without higher analytical purity claims. size supports dyeing trials, analytical reference work, formulation studies and teaching laboratories that need a practical quantity of Direct Orange 26. Formula and molar mass values enable consistent preparation of stock solutions and comparison across batches. Within the chemicals and biochemicals range from manufacturer Carl ROTH, this colorant serves groups working on textile-related chemistry, dye characterisation or sulfonated azo systems. Handle according to good laboratory practice for organic dyes and sulfonated aromatics, review institutional safety guidance before use, and base quantitative work on the stated molecular mass of 756,67 g/mol.

Questions about Direct Orange 26, technical, 100 g
What is this article?
Direct Orange 26, technical, 100 g 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.
