{"product_id":"c-i-reactive-red-120-2ha6-2ha6","title":"C.I.Reactive Red 120, 50 g","description":"\u003cp\u003eC.I. Reactive Red 120 is a reactive azo dye reagent provided for laboratory dyeing studies, analytical work, and biochemical applications. It is registered under CAS number 61951-82-4, with empirical formula C₄₄H₃₀O₂₀N₁₄S₆Cl₂ and a molar mass of 1338,09 g\/mol. These identity parameters support accurate preparation of stock solutions and reproducible colour chemistry experiments. The product is As a reactive red colourant, it is used where covalent fixation behaviour and chromophore performance are under investigation. Material from manufacturer Carl ROTH arrives with the core physicochemical data needed for laboratory documentation and inventory control. Clear CAS, formula, and molar-mass information help analysts calculate concentrations and compare batches. Handle according to good laboratory practice for reactive dyes and sulfonated organic colourants. balances working quantity with manageable storage for specialised dye chemistry programmes in academic and industrial laboratories.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/organic-building-blocks-and-synthesis-reagents\"\u003eOrganic building blocks \u0026amp; synthesis reagents\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/collections\/organic-chemicals-and-synthesis-reagents\"\u003eOrganic chemicals \u0026amp; synthesis reagents\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eColour: red to black mixed gray\/white particles\u003c\/li\u003e\n\u003cli\u003eForm: crystalline powder\u003c\/li\u003e\n\u003cli\u003eMelting point: ≥300 °C\u003c\/li\u003e\n\u003cli\u003eCAS number: 61951-82-4\u003c\/li\u003e\n\u003cli\u003ePack sizes: 50 g, 100 g, 250 g\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₄₄H₃₀O₂₀N₁₄S₆Cl₂\u003c\/li\u003e\n\u003cli\u003eMolar mass: 1338,09 g\/mol\u003c\/li\u003e\n\u003cli\u003eChemical name: C.I.
