{"product_id":"reichardt-s-dye-2x0e-2x0e","title":"Reichardt's dye, 1 g","description":"\u003cp\u003eReichardt's dye is a well-established solvatochromic indicator compound identified by CAS number 10081-39-7 and the empirical formula C₄₁H₂₉NO. With a molar mass of 551,68 g\/mol, it provides a clearly defined molecular basis for quantitative and spectroscopic laboratory applications. The dye is widely employed to probe solvent polarity, medium effects, and microenvironment characterisation through pronounced shifts in its charge-transfer absorption band. Specification data from manufacturer Carl ROTH include CAS registry number, empirical formula, and molar mass, enabling reliable identity confirmation and documentation. This presentation is intended for trained users who require a classical betaine dye for polarity scales, solvent studies, or related photophysical investigations under standard laboratory conditions.\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\u003eColour: dark blue to black\u003c\/li\u003e\n\u003cli\u003eForm: powder\u003c\/li\u003e\n\u003cli\u003eCarbon (C): 79.4-99.1 %\u003c\/li\u003e\n\u003cli\u003eNitrogen content (N): 2.1-2.8 %\u003c\/li\u003e\n\u003cli\u003eIR-spectrum: complies\u003c\/li\u003e\n\u003cli\u003eCAS number: 10081-39-7\u003c\/li\u003e\n\u003cli\u003ePack sizes: 1 g, 2.5 g, 5 g\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₄₁H₂₉NO\u003c\/li\u003e\n\u003cli\u003eMolar mass: 551,68 g\/mol\u003c\/li\u003e\n\u003cli\u003eProduct class: Biochemical \/ dye\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2X0E-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMjIyMHxhcHBsaWNhdGlvbi9wZGZ8YURrNEwyZzVOUzg1TWpVME56WXhNalkzTWpNd0wxTlFSVnBmTWxnd1JWOUZUaTV3WkdZfGI1OWQ2ZTFjNjIwMDgzMTMyZjlhZGNmM2RhOWQ4Y2MyOGY5N2RjODNkZWRiMzQxOWFiZmU3MjNjNGFlZmM5MmQ\" 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-2X0E-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyMzc5MDF8YXBwbGljYXRpb24vcGRmfGFEQmlMMmhtTUM4NU1qQTVPVEV5T0RVeU5URXdMMU5FUWw4eVdEQkZYMFJGWDBWT0xuQmtaZ3xjZDZjMDgyYTAwOWVhOWQ0Y2EzYmNiODZmNGUwMWEzYTIyYzI2NDY0YmEzNzNmZjZiMmQ0NjE3YzJlNWY5NmNh\" 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":"1 g \/ 1 piece","offer_id":56147863863628,"sku":"2X0E.3","price":385.95,"currency_code":"EUR","in_stock":true},{"title":"1 g \/ 6+ pieces","offer_id":56147863896396,"sku":"2X0E.3","price":385.95,"currency_code":"EUR","in_stock":true},{"title":"1 g \/ 24+ pieces","offer_id":56147863929164,"sku":"2X0E.3","price":385.95,"currency_code":"EUR","in_stock":true},{"title":"2.5 g \/ 1 piece","offer_id":56147863961932,"sku":"2X0E.4","price":805.2,"currency_code":"EUR","in_stock":true},{"title":"2.5 g \/ 6+ pieces","offer_id":56147863994700,"sku":"2X0E.4","price":764.94,"currency_code":"EUR","in_stock":true},{"title":"2.5 g \/ 24+ pieces","offer_id":56147864027468,"sku":"2X0E.4","price":724.68,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 1 piece","offer_id":56147864060236,"sku":"2X0E.5","price":1342.7,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 6+ pieces","offer_id":56147864093004,"sku":"2X0E.5","price":1275.57,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 24+ pieces","offer_id":56147864125772,"sku":"2X0E.5","price":1208.43,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2X0E-SF_a9bc3fe3-e6a5-426a-84ba-389c1c1d850a.jpg?v=1766419583","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/reichardt-s-dye-2x0e-2x0e","provider":"Luminix Health","version":"1.0","type":"link"}
