{"product_id":"c-i-vat-yellow-2-2y34-2y34","title":"C.I.Vat Yellow 2, min. 95 %, 500 mg","description":"\u003cp\u003eC.I. Vat Yellow 2 is a vat dye compound supplied at a minimum purity of 95 %, with CAS number 129-09-9 and the empirical formula C₂₈H₁₄N₂O₂S₂. Its molar mass is 474,56 g\/mol and the flash point is given as 393,6 °C, providing essential physicochemical reference points for laboratory handling and documentation. sourced from manufacturer Carl ROTH, this yellow vat colourant supports colour chemistry research, pigment characterisation and stoichiometric work where a defined organic structure and stated minimum assay are required. The combination of CAS identity, empirical formula and molar mass enables reliable calculation of concentrations and comparison across batches or methods. Clear specification of purity and thermal data helps integrate C.I. Vat Yellow 2 into protocols that demand traceable dye materials without unnecessary bulk inventory.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-nl\/collections\/organic-building-blocks-and-synthesis-reagents\"\u003eOrganic building blocks \u0026amp; synthesis reagents\u003c\/a\u003e, in \u003ca href=\"\/en-nl\/collections\/organic-chemicals-and-synthesis-reagents\"\u003eOrganic chemicals \u0026amp; synthesis reagents\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePurity (GC): reported (%)\u003c\/li\u003e\n\u003cli\u003ePurity (HPLC): reported (%)\u003c\/li\u003e\n\u003cli\u003eIR-spectrum: corresponds to reference spectrum\u003c\/li\u003e\n\u003cli\u003epH value: reported ()\u003c\/li\u003e\n\u003cli\u003eAssay (TLC): reported (%)\u003c\/li\u003e\n\u003cli\u003eContent (acidim.): reported (%)\u003c\/li\u003e\n\u003cli\u003eAssay: reported (%)\u003c\/li\u003e\n\u003cli\u003eMelting point: reported (°C)\u003c\/li\u003e\n\u003cli\u003eColour: reported\u003c\/li\u003e\n\u003cli\u003eForm: reported\u003c\/li\u003e\n\u003cli\u003eCAS number: 129-09-9\u003c\/li\u003e\n\u003cli\u003ePack sizes: 500 mg, 1 g, 2 g\u003c\/li\u003e\n\u003cli\u003ePurity: min. 95 %\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₂₈H₁₄N₂O₂S₂\u003c\/li\u003e\n\u003cli\u003eMolar mass: 474,56 g\/mol\u003c\/li\u003e\n\u003cli\u003eFlash point: 393,6 °C\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2Y34-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwNjIxOHxhcHBsaWNhdGlvbi9wZGZ8YUdVekwyZzRPUzg1TWpVME56YzJNalF5TWpBMkwxTlFSVnBmTWxrek5GOUZUaTV3WkdZfDgwM2NkNWQ1ODM1YjRhMDRmNTdkMWM4YmRkODQ4MDE4NWFmMDlkYmI1NTgyYTQwM2JhYjMyZTYxODJhYTNkOWM\" 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-2Y34-DE-DE.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3w3ODY1MHxhcHBsaWNhdGlvbi9wZGZ8YUdSa0wyZzJNQzg1TVRrMk16SXlPVGM1T0Rjd0wxTkVRbDh5V1RNMFgwUkZYMFJGTG5Ca1pnfGJhMGM5NTJkNzY4YmY3YmU0ZDMxYmM0NGRjYzU3OGVhZGM0NDBjZmJjNmI3NTQwZmVjZGNhMmM1OGU2NDU1NWY\" 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":"500 mg \/ 1 piece","offer_id":56148152385868,"sku":"2Y34.2","price":181.7,"currency_code":"EUR","in_stock":true},{"title":"500 mg \/ 6+ pieces","offer_id":56148152418636,"sku":"2Y34.2","price":172.62,"currency_code":"EUR","in_stock":true},{"title":"500 mg \/ 24+ pieces","offer_id":56148152451404,"sku":"2Y34.2","price":163.53,"currency_code":"EUR","in_stock":true},{"title":"1 g \/ 1 piece","offer_id":56148152484172,"sku":"2Y34.3","price":317.15,"currency_code":"EUR","in_stock":true},{"title":"1 g \/ 6+ pieces","offer_id":56148152516940,"sku":"2Y34.3","price":301.29,"currency_code":"EUR","in_stock":true},{"title":"1 g \/ 24+ pieces","offer_id":56148152549708,"sku":"2Y34.3","price":285.44,"currency_code":"EUR","in_stock":true},{"title":"2 g \/ 1 piece","offer_id":56148152582476,"sku":"2Y34.4","price":575.15,"currency_code":"EUR","in_stock":true},{"title":"2 g \/ 6+ pieces","offer_id":56148152615244,"sku":"2Y34.4","price":546.39,"currency_code":"EUR","in_stock":true},{"title":"2 g \/ 24+ pieces","offer_id":56148152648012,"sku":"2Y34.4","price":517.64,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2Y34-SF_1a21e201-54ab-4fe2-a97f-41f85f308636.jpg?v=1766419995","url":"https:\/\/www.luminixhealth.com\/en-nl\/products\/c-i-vat-yellow-2-2y34-2y34","provider":"Luminix Health","version":"1.0","type":"link"}
