{"product_id":"disperse-blue-183-2k3h-2k3h","title":"Disperse blue 183, 250 g","description":"\u003cp\u003eDisperse blue 183 is an organic colorant reagent supplied for laboratory chemical and biochemical applications. It is registered under CAS number 2309-94-6, with the empirical formula C₂₀H₂₁BrN₆O₃ and a molar mass of 473,32 g\/mol. This listing provides, giving sufficient material for dyeing trials, analytical comparison, formulation screening, and educational or industrial laboratory work that requires a defined disperse blue dye. Physical identity is anchored by the stated molecular formula and molar mass, enabling accurate stoichiometric calculation and documentation in research notebooks and quality records. The product is offered from manufacturer Carl ROTH within its chemicals portfolio. Disperse dyes of this class are commonly employed when laboratories need reproducible coloration behaviour on hydrophobic substrates or when reference samples are prepared for spectroscopic and chromatographic methods. Consistent CAS and formula data support inventory control, safety assessment, and cross-site transfer of methods where the same dye identity must be maintained.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/homogenisers-and-dispersers\"\u003eHomogenisers \u0026amp; dispersers\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/collections\/stirring-shaking-and-mixing\"\u003eStirring, shaking \u0026amp; mixing\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eColour: blue to deep blue\u003c\/li\u003e\n\u003cli\u003eForm: powder\u003c\/li\u003e\n\u003cli\u003eColor intensity: 97-103 %\u003c\/li\u003e\n\u003cli\u003eCAS number: 2309-94-6\u003c\/li\u003e\n\u003cli\u003ePack sizes: 250 g, 500 g, 1 kg\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₂₀H₂₁BrN₆O₃\u003c\/li\u003e\n\u003cli\u003eMolar mass: 473,32 g\/mol\u003c\/li\u003e\n\u003cli\u003eProduct type: Disperse blue dye\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2K3H-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMDQ4MHxhcHBsaWNhdGlvbi9wZGZ8YURabUwyZ3dNeTg1TWpVME5EWXpOakF5TnpFNEwxTlFSVnBmTWtzelNGOUZUaTV3WkdZfDM4ZTc3M2E4MmFlMTNhYjMzZTEwYWZiZDlhYzY5OGNlMTJlMWU2ZTcyYjNjYTUxOGYxMjdlMGExM2Q0NDljMTg\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" title=\"Technical sheet PDF\" aria-label=\"Technical sheet PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eSafety Data Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SDB-2K3H-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyMzk3MTB8YXBwbGljYXRpb24vcGRmfGFHTTBMMmcyTWk4NU1qQTJORFl5T1RBMk16azRMMU5FUWw4eVN6TklYMFJGWDBWT0xuQmtaZ3xiOTg2NTgxZGRhZjE1YzU0MjJlM2NmYWI4YmVlMzJiZDRjNDBlZTNjNDY4ZGFmNWYzY2E5MzIwOTdiZjFjMmU5\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" title=\"SDS PDF\" aria-label=\"SDS PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Carl Roth","offers":[{"title":"250 g \/ 1 piece","offer_id":56137219375436,"sku":"2K3H.3","price":332.2,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 6+ pieces","offer_id":56137219408204,"sku":"2K3H.3","price":315.59,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 24+ pieces","offer_id":56137219440972,"sku":"2K3H.3","price":298.98,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 1 piece","offer_id":56137219473740,"sku":"2K3H.4","price":557.95,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 6+ pieces","offer_id":56137219506508,"sku":"2K3H.4","price":530.05,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 24+ pieces","offer_id":56137219539276,"sku":"2K3H.4","price":502.16,"currency_code":"EUR","in_stock":true},{"title":"1 kg \/ 1 piece","offer_id":56137219572044,"sku":"2K3H.5","price":934.2,"currency_code":"EUR","in_stock":true},{"title":"1 kg \/ 6+ pieces","offer_id":56137219604812,"sku":"2K3H.5","price":934.2,"currency_code":"EUR","in_stock":true},{"title":"1 kg \/ 24+ pieces","offer_id":56137219637580,"sku":"2K3H.5","price":934.2,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2K3H-SF_4c62c034-4099-42e8-89d0-88ae014babb8.jpg?v=1766417705","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/disperse-blue-183-2k3h-2k3h","provider":"Luminix Health","version":"1.0","type":"link"}
