It has a molar mass of 350,45 g\/mol and a density of 1,213 g\/cm³, This solvent-soluble blue colourant from manufacturer Carl ROTH carries EG number 241-379-4 and supports reproducible preparation of dye solutions, stock standards, and staining baths where the C.I. 61554 identity is specified. Typical laboratory uses include lipophilic phase colouration, thin-layer visualisation, and comparative colour work that relies on a defined pure grade of Sudan Blue II. The compact glass pack suits method development, small-scale staining series, and reference inventory without excess bulk. Stated molar mass and density values aid concentration calculations and formulation of working solutions. Users can integrate the dye into established protocols for solvent-based blue colouration while relying on the listed purity grade and identity data. Standard laboratory handling for solid organic dyes applies throughout use and storage on the bench.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article belongs on \u003ca

It is identified by CAS number 2611-82-7 and the empirical formula C₂₀H₁₁N₂O₁₀S₃Na₃, with a molar mass of 604,47 g\/mol and a density of 1,772 g\/cm³. The material is Typical applications include staining protocols, colour marking and dye chemistry work where a defined Colour Index reference is required. Available from manufacturer Carl ROTH and listed under EG number 220-036-2, this extra pure grade suits laboratories that need a reliable source of Ponceau 4R for routine experimental procedures. Documented physicochemical data together with the compact glass packaging make it a practical addition to dye and indicator inventories used across analytical and life-science workflows.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article belongs on \u003ca href=\"\/en-be\/collections\/microscopy-stains-and-staining-solutions\"\u003eMicroscopy stains \u0026amp;

Identified by CAS number 50517-12-9, it has the empirical formula C₁₁H₁₃ClN₂ and a molar mass of 208,69 g\/mol. The compound exhibits a boiling point of 327,4 °C, supporting handling and process planning in controlled laboratory workflows. As an indole-related building block, 6-chlorogramine is relevant in studies of substituted tryptamine scaffolds and related heterocyclic chemistry. Material from manufacturer Carl ROTH is offered for laboratories that require clearly specified reagents with transparent identity data. Typical use cases include exploratory organic synthesis, structure–activity investigations, and preparation of further functionalized intermediates. The defined assay, molecular formula, and physical constants help analysts and chemists document reagents accurately in protocols and inventory systems. Suitable for research environments working with specialty biochemicals and fine chemicals where consistent lot identity and compact pack formats are preferred.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article belongs on \u003ca href=\"\/en-be\/collections\/microscopy-stains-and-staining-solutions\"\u003eMicroscopy stains \u0026amp;
