It is identified by CAS number 4395-65-7 and has the empirical formula C₂₀H₁₄N₂O₂, corresponding to a molar mass of 314,34 g\/mol. This solvent blue dye is offered in a convenient 1 g pack size, making it suitable for analytical preparations, reference work, and small-scale experimental use where controlled quantities of a defined colourant are required. The material belongs to the solvent dye class and is handled as a fine chemical within biochemical and general laboratory chemical assortments. Sourced from manufacturer Carl ROTH, the product is presented with clearly stated identity data so that formulators and researchers can match it to established dye nomenclature and CAS-based inventory systems. Its defined molecular mass and minimum assay support reproducible weighing and solution preparation in research, quality-control, and method-development settings. The 1 g unit is practical for stock solutions, staining trials, and comparative dye studies without excess material on hand. Overall, C.I.

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\/dyes-and-pigments\"\u003eDyes \u0026amp; pigments\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/collections\/dyes-stains-and-indicators\"\u003eDyes, stains \u0026amp; indicators\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":887.49,"currency_code":"EUR","in_stock":true},{"title":"1 kg \/ 24+ pieces","offer_id":56137219637580,"sku":"2K3H.5","price":840.78,"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"},{"product_id":"disperse-red-1-2k3p-2k3p","title":"Disperse red 1, 25 g","description":"\u003cp\u003eDisperse red 1 is a research chemical dye material with CAS number 2872-52-8, empirical formula C₁₆H₁₈N₄O₃, and a molar mass of 314,34 g\/mol.

The material has a molar mass of 438,46 g\/mol, a boiling point of 665,8 °C and a flash point of 356,4 °C, reflecting a thermally robust aromatic structure suited to colourant and specialty-chemical studies. Its azo- and heteroatom-rich scaffold is relevant for textile dye research, pigment formulation trials and analytical reference work where a defined red disperse dye is required. Documented molar mass and thermal data assist inventory control, process safety assessment and formulation planning.
