{"product_id":"charcoal-x865-x865","title":"Charcoal, p.a., 250 g, plastic","description":"\u003cp\u003eCharcoal is a p.a. grade carbon material intended for laboratory filtration, decolourisation and adsorption applications. Identified by CAS number 7440-44-0 and empirical formula C, it has a molar mass of 12,01 g\/mol and is supplied as a practical for everyday bench use. In analytical and preparative chemistry, charcoal is widely employed to remove coloured impurities from organic solutions, to polish reaction mixtures and to support sample clean-up before spectroscopic or chromatographic measurement. This reagent from manufacturer Carl ROTH fits workflows that specify analytical-grade carbon rather than technical charcoal. Typical uses include treatment of crystallisation liquors, clarification of extracts and teaching experiments that demonstrate surface adsorption. The EG number 231-153-3 provides a clear regulatory identity for documentation and inventory systems. Laboratories working across organic synthesis, natural-product isolation and general wet chemistry can rely on this p.a. charcoal when a defined elemental carbon source is required without additional functional claims beyond the stated analytical grade.\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\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSubstances soluble in ethanol: ≤0,2 %\u003c\/li\u003e\n\u003cli\u003eSubstances soluble in HCl: ≤1,0 %\u003c\/li\u003e\n\u003cli\u003eSubstances soluble in H2O: ≤0,2 %\u003c\/li\u003e\n\u003cli\u003eMethylene blue adsorption (0,15 % solution): ≥100 ml\/g\u003c\/li\u003e\n\u003cli\u003eChloride (Cl): ≤0,01 %\u003c\/li\u003e\n\u003cli\u003eSulphate (SO4): ≤0,01 %\u003c\/li\u003e\n\u003cli\u003eSulphide (S): complies\u003c\/li\u003e\n\u003cli\u003eLead (Pb): ≤0,002 %\u003c\/li\u003e\n\u003cli\u003eCalcium (Ca): ≤0,05 %\u003c\/li\u003e\n\u003cli\u003eIron (Fe): ≤0,025 %\u003c\/li\u003e\n\u003cli\u003eCAS number: 7440-44-0\u003c\/li\u003e\n\u003cli\u003ePack sizes: 250 g, 500 g, 1 kg\u003c\/li\u003e\n\u003cli\u003eEG nr.: 231-153-3\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C\u003c\/li\u003e\n\u003cli\u003eMolar mass: 12,01 g\/mol\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-X865-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwNjk1OHxhcHBsaWNhdGlvbi9wZGZ8YURJeUwyZzFaQzg1TWpVMU1ERTJNREExTmpZeUwxTlFSVnBmV0RnMk5WOUZUaTV3WkdZfGM1OGVmNzQzOGJkMDM4Zjg0N2NjNWFhNWI2NTQxYTdiNmMyMzk0N2U2YWE5ZWNmNWVkM2U3ODJiYzQ4YThmODM\" 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-X865-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyNDgwMTV8YXBwbGljYXRpb24vcGRmfGFEbGhMMmhoTlM4NU1qQTJPVEEwT0RneE1UZ3lMMU5FUWw5WU9EWTFYMFJGWDBWT0xuQmtaZ3xhNTU5MGE3MWVmZGNjYjVjOTBmY2YxZmQyNTI5MDZhZjBmZjNlYzhlNjQxMTcxZDdjMTY4MWRjYWQ0ZTg4NGY2\" 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":56186630635852,"sku":"X865.1","price":36.45,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 6+ pieces","offer_id":56186630668620,"sku":"X865.1","price":34.63,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 24+ pieces","offer_id":56186630701388,"sku":"X865.1","price":32.81,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 1 piece","offer_id":56186630734156,"sku":"X865.2","price":57.95,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 6+ pieces","offer_id":56186630766924,"sku":"X865.2","price":55.05,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 24+ pieces","offer_id":56186630799692,"sku":"X865.2","price":52.16,"currency_code":"EUR","in_stock":true},{"title":"1 kg \/ 1 piece","offer_id":56186630832460,"sku":"X865.3","price":104.2,"currency_code":"EUR","in_stock":true},{"title":"1 kg \/ 6+ pieces","offer_id":56186630865228,"sku":"X865.3","price":104.2,"currency_code":"EUR","in_stock":true},{"title":"1 kg \/ 24+ pieces","offer_id":56186630897996,"sku":"X865.3","price":104.2,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-X865_2a430ffb-1f5c-4783-ae11-111b5246e21b.jpg?v=1766500558","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/charcoal-x865-x865","provider":"Luminix Health","version":"1.0","type":"link"}
