{"product_id":"reactive-blue-5-2x06-2x06","title":"Reactive Blue 5, 25 g","description":"\u003cp\u003eIt is registered under CAS number 16823-51-1 and characterised by the empirical formula C₂₉H₂₀ClN₇O₁₁S₃ with a molar mass of 774,16 g\/mol, enabling precise preparation of solutions and reproducible experimental setups. This material is intended for research environments that require a well-defined reactive blue dye for staining, binding studies, or method development. Available from manufacturer Carl ROTH as part of the chemicals and biochemicals portfolio, it supports routine laboratory handling with a quantity suitable for repeated trials and protocol optimisation. The stated molecular weight and formula assist documentation, safety assessment, and calculation of working concentrations. Laboratories engaged in dye chemistry, textile-related model systems, or broader biochemical colourant research can incorporate this grade into analytical and preparative workflows. Clear identity data and a convenient solid pack size help streamline ordering, storage planning, and day-to-day use at the bench without unnecessary excess material.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/organic-building-blocks-and-synthesis-reagents\"\u003eOrganic building blocks \u0026amp; synthesis reagents\u003c\/a\u003e, in \u003ca href=\"\/en-be\/collections\/organic-chemicals-and-synthesis-reagents\"\u003eOrganic chemicals \u0026amp; synthesis reagents\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIR-spectrum: corresponds to reference spectrum\u003c\/li\u003e\n\u003cli\u003eColour: dark blue to black\u003c\/li\u003e\n\u003cli\u003eForm: powder\u003c\/li\u003e\n\u003cli\u003eColor intensity: 98 to 102 %\u003c\/li\u003e\n\u003cli\u003eCAS number: 16823-51-1\u003c\/li\u003e\n\u003cli\u003ePack sizes: 25 g, 50 g, 100 g, 250 g\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₂₉H₂₀ClN₇O₁₁S₃\u003c\/li\u003e\n\u003cli\u003eMolar mass: 774,16 g\/mol\u003c\/li\u003e\n\u003cli\u003eProduct type: Biochemical dye\u003c\/li\u003e\n\u003cli\u003eApplication area: Laboratory research\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2X06-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMTkxM3xhcHBsaWNhdGlvbi9wZGZ8YUdNM0wyZzBNeTg1TWpVME56WXdPVGN5TXpFNEwxTlFSVnBmTWxnd05sOUZUaTV3WkdZfDAxZGYzYzBmNGFjZGUzM2RhNjU2MzYzMDAzNTQ5ZmM2NjM1MTZkZGZjMDAwMzEzZDkwMzhkMmMyNzY1OTdjMDg\" 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-2X06-DE-DE.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3w3ODY1MHxhcHBsaWNhdGlvbi9wZGZ8YURRMEwyZzNNeTg1TVRrMk1qa3pNVFl3T1Rrd0wxTkVRbDh5V0RBMlgwUkZYMFJGTG5Ca1pnfDIyNzlmMTFhNzgyMzIwODBkZmIzNmFkZDA3YjczOWVhN2RkZTFlOTcwNWY4ZTY3ZTg0ZDk5ZTdkNWE0MzUyOTM\" 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":"25 g \/ 1 piece","offer_id":56147860521292,"sku":"2X06.2","price":220.4,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 6+ pieces","offer_id":56147860554060,"sku":"2X06.2","price":209.38,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 24+ pieces","offer_id":56147860586828,"sku":"2X06.2","price":198.36,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 1 piece","offer_id":56147860619596,"sku":"2X06.3","price":349.4,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 6+ pieces","offer_id":56147860652364,"sku":"2X06.3","price":331.93,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 24+ pieces","offer_id":56147860685132,"sku":"2X06.3","price":314.46,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 1 piece","offer_id":56147860717900,"sku":"2X06.4","price":521.4,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 6+ pieces","offer_id":56147860750668,"sku":"2X06.4","price":495.33,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 24+ pieces","offer_id":56147860783436,"sku":"2X06.4","price":469.26,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 1 piece","offer_id":56147860816204,"sku":"2X06.5","price":951.4,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 6+ pieces","offer_id":56147860848972,"sku":"2X06.5","price":903.83,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 24+ pieces","offer_id":56147860881740,"sku":"2X06.5","price":856.26,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2X06-SF_d75858db-dc97-44ec-a57a-4a8569d9502a.jpg?v=1766419580","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/reactive-blue-5-2x06-2x06","provider":"Luminix Health","version":"1.0","type":"link"}
