{"product_id":"coumarin-5284","title":"Coumarin, ROTICHROM® GC, 1 g, glass","description":"\u003cp\u003eCoumarin ROTICHROM® GC is a gas-chromatography reference substance with empirical formula C₉H₆O₂, CAS number 91-64-5 and EG number 202-086-7. The molar mass is 146,15 g\/mol, density 0,935 g\/cm³, flash point 162 °C and boiling point 298 °C. Packed as 1 g in glass, this lactone is intended for GC calibration, retention-index work and qualitative or quantitative reference applications in chromatographic laboratories. The ROTICHROM® GC grade from manufacturer Carl ROTH is positioned for analytical workflows that demand defined identity and consistent performance as a reference material. Coumarin is frequently used when establishing system suitability, verifying detector response or supporting method development in fragrance, natural-product and organic-analysis contexts. The small 1 g glass unit minimises waste while providing sufficient material for repeated standard preparation. Store and handle under controlled laboratory conditions appropriate to organic solids, and consult the safety documentation for classification, UN handling notes and recommended precautions before opening the vial or preparing solutions.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/chromatography-standards\"\u003eChromatography standards (GC, HPLC, pesticides)\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/collections\/analytical-standards-and-reference-materials\"\u003eAnalytical standards \u0026amp; reference materials\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePurity (GC): ≥99 %\u003c\/li\u003e\n\u003cli\u003eCAS number: 91-64-5\u003c\/li\u003e\n\u003cli\u003ePack size: 1 g glass\u003c\/li\u003e\n\u003cli\u003eEG nr.: 202-086-7\u003c\/li\u003e\n\u003cli\u003eMolar mass: 146,15 g\/mol\u003c\/li\u003e\n\u003cli\u003eStorage temperature: +4 °C\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-5284-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMjE3OXxhcHBsaWNhdGlvbi9wZGZ8YURJNEwyZzBPUzg1TWpVME9EZzRORGN5TmpBMkwxTlFSVnBmTlRJNE5GOUZUaTV3WkdZfDU4ODBkMTM1YWFlOTc2OTI1NzU1MjUwMjg2NjNlMzc0MmFkMWRhMjIwOTI0MzJiZTJhODU4NTNmYzRjMTZlMzI\" 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-5284-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wzMzA2NDJ8YXBwbGljYXRpb24vcGRmfGFHSTRMMmhtTUM4NU1qQTJOekl3TXprM016UXlMMU5FUWw4MU1qZzBYMFJGWDBWT0xuQmtaZ3wzMGE4NTQxZjU4ZWE5YWYyMTU0YzdmNjJiYmM3OTI4NDM4NWRiNTM3MmNjNjEyZTIyMmM3ZTczYmJiOGFiNjEx\" 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":56165270978892,"sku":"5284.1","price":142.45,"currency_code":"EUR","in_stock":true},{"title":"1 g \/ 6+ pieces","offer_id":56165271011660,"sku":"5284.1","price":135.33,"currency_code":"EUR","in_stock":true},{"title":"1 g \/ 24+ pieces","offer_id":56165271044428,"sku":"5284.1","price":128.21,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/7942-SF-1000Wx1000H_33829158-93ba-4417-af6d-ef04ec73a71e.jpg?v=1766439734","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/coumarin-5284","provider":"Luminix Health","version":"1.0","type":"link"}
