{"product_id":"coumestrol-2h92-2h92","title":"Coumestrol, min. 95 %, 10 mg","description":"\u003cp\u003eCoumestrol is a biochemical reagent supplied at a minimum purity of 95 % for laboratory use. It is defined by CAS number 479-13-0 and the empirical formula C₁₅H₈O₅, with a molar mass of 268,22 g\/mol. The material is offered from manufacturer Carl ROTH as part of a focused biochemicals range intended for research and analytical environments. Clear identification via CAS and molecular formula helps laboratories confirm identity against internal specifications and literature references before use. The stated molar mass facilitates stoichiometric calculations for solution preparation and assay design. Packaged as a small solid portion, the product suits method development, reference work and exploratory studies that need only limited amounts of material. Consistent labelling of purity, formula and CAS supports documentation, inventory control and traceability within regulated or quality-managed laboratory settings.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/organic-building-blocks-and-synthesis-reagents\"\u003eOrganic building blocks \u0026amp; synthesis reagents\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/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\u003eCAS number: 479-13-0\u003c\/li\u003e\n\u003cli\u003ePack sizes: 10 mg, 25 mg, 50 mg, 100 mg\u003c\/li\u003e\n\u003cli\u003ePurity: min. 95 %\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₁₅H₈O₅\u003c\/li\u003e\n\u003cli\u003eMolar mass: 268,22 g\/mol\u003c\/li\u003e\n\u003cli\u003eStorage temperature: +2 to +8 °C\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2H92-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMzAxOXxhcHBsaWNhdGlvbi9wZGZ8YUdGaUwyZ3hOUzg1TWpVME5qZzRNRFl6TlRFNEwxTlFSVnBmTWtnNU1sOUZUaTV3WkdZfGUwZTFmYjA3ZGIzZDlhNjYwZGEzODBiNWMzZmQwZDAwMzAwNGRjY2E0YmY0YTExNDYzMjFiYjBhMWRlM2MwNGU\" 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\u003c\/ul\u003e","brand":"Carl Roth","offers":[{"title":"10 mg \/ 1 piece","offer_id":56136713568588,"sku":"2H92.2","price":192.45,"currency_code":"EUR","in_stock":true},{"title":"10 mg \/ 6+ pieces","offer_id":56136713601356,"sku":"2H92.2","price":182.83,"currency_code":"EUR","in_stock":true},{"title":"10 mg \/ 24+ pieces","offer_id":56136713634124,"sku":"2H92.2","price":173.21,"currency_code":"EUR","in_stock":true},{"title":"25 mg \/ 1 piece","offer_id":56136713666892,"sku":"2H92.3","price":289.2,"currency_code":"EUR","in_stock":true},{"title":"25 mg \/ 6+ pieces","offer_id":56136713699660,"sku":"2H92.3","price":274.74,"currency_code":"EUR","in_stock":true},{"title":"25 mg \/ 24+ pieces","offer_id":56136713732428,"sku":"2H92.3","price":260.28,"currency_code":"EUR","in_stock":true},{"title":"50 mg \/ 1 piece","offer_id":56136713765196,"sku":"2H92.4","price":306.4,"currency_code":"EUR","in_stock":true},{"title":"50 mg \/ 6+ pieces","offer_id":56136713797964,"sku":"2H92.4","price":291.08,"currency_code":"EUR","in_stock":true},{"title":"50 mg \/ 24+ pieces","offer_id":56136713830732,"sku":"2H92.4","price":275.76,"currency_code":"EUR","in_stock":true},{"title":"100 mg \/ 1 piece","offer_id":56136713863500,"sku":"2H92.5","price":482.7,"currency_code":"EUR","in_stock":true},{"title":"100 mg \/ 6+ pieces","offer_id":56136713896268,"sku":"2H92.5","price":458.57,"currency_code":"EUR","in_stock":true},{"title":"100 mg \/ 24+ pieces","offer_id":56136713929036,"sku":"2H92.5","price":434.43,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2H92-SF_c8541699-6f11-4be9-b2a5-128c9ee89f48.jpg?v=1766417462","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/coumestrol-2h92-2h92","provider":"Luminix Health","version":"1.0","type":"link"}
