{"product_id":"c-i-basic-blue-8-2ea2-2ea2","title":"C.I.Basic blue 8, min. 95 %, 25 g","description":"\u003cp\u003eC.I. Basic Blue 8 is a cationic dye substance intended for laboratory chemical and biochemical use. It is supplied at a minimum purity of 95 %, identified by CAS number 2185-87-7, and characterised by the empirical formula C₃₄H₃₄N₃Cl with a molar mass of 623,57 g\/mol. These parameters allow unambiguous linkage to Colour Index nomenclature, analytical methods, and research protocols involving basic blue dyes. The product is offered in a 25 g pack size, corresponding to a net weight of 0,043 kg, which accommodates staining trials, formulation checks, and repeated small- to medium-scale laboratory applications. As a defined organic salt with an extended conjugated aromatic system, it is relevant where dye identity, molar mass, and batch documentation must remain consistent across experiments. Material from manufacturer Carl ROTH sits within the chemicals and biochemicals range for research environments. Users can rely on the stated CAS number, molecular formula, purity level, and pack configuration when preparing working solutions, comparing dye lots, or recording reagent data in laboratory information systems, supporting transparent handling of this Colour Index basic blue compound.\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\u003eAssay: ≥ 95 %\u003c\/li\u003e\n\u003cli\u003eColour: reported\u003c\/li\u003e\n\u003cli\u003eForm: reported\u003c\/li\u003e\n\u003cli\u003eCAS number: 2185-87-7\u003c\/li\u003e\n\u003cli\u003ePack size: 25 g\u003c\/li\u003e\n\u003cli\u003ePurity: min. 95 %\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₃₄H₃₄N₃Cl\u003c\/li\u003e\n\u003cli\u003eMolar mass: 623,57 g\/mol\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2EA2-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMjQ0NXxhcHBsaWNhdGlvbi9wZGZ8YURZM0wyZzNOQzg1TWpVME5qYzBOemt5TkRjNEwxTlFSVnBmTWtWQk1sOUZUaTV3WkdZfDQ3ZWEzNDY3NTk5ZmUwOTM4ZTA4MjQ0NWZiZDk5MmVjZjUyMmM4MjVlNjIxOTg5YzU4NDRjYTZiNTk3NTEyMWM\" 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-2EA2-DE-DE.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3w3ODY1MHxhcHBsaWNhdGlvbi9wZGZ8YURRMkwyaGpPUzg1TVRrMk1URXpNRFk0TURZeUwxTkVRbDh5UlVFeVgwUkZYMFJGTG5Ca1pnfDAyNjlmYWZmM2QwOWI3NTM5NGI5YzdiZDVkMjQ5NzM4ODI4N2UzZTEzNzliOGMyMjJhN2E4NTMwODhhNDlhM2I\" 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":56133981831500,"sku":"2EA2.3","price":349.4,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 6+ pieces","offer_id":56133981864268,"sku":"2EA2.3","price":331.93,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 24+ pieces","offer_id":56133981897036,"sku":"2EA2.3","price":314.46,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2EA2-SF_4e75dd37-5e6a-4f1b-81e2-b4450184624b.jpg?v=1766416961","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/c-i-basic-blue-8-2ea2-2ea2","provider":"Luminix Health","version":"1.0","type":"link"}
