{"product_id":"l-dehydroascorbic-acid-303c-303c","title":"L-Dehydroascorbic acid, min. 95 %, 1 g","description":"\u003cp\u003eL-Dehydroascorbic acid is a biochemical reagent supplied at a minimum purity of 95 % for laboratory research applications. Identified by CAS number 490-83-5 and empirical formula C₆H₆O₆, it has a molar mass of 174,11 g\/mol. The product is This grade from manufacturer Carl ROTH supports experiments in redox chemistry, vitamin C metabolism pathways, and related assay development where a defined L-dehydroascorbic acid standard is required. Clear specification of purity and molecular data facilitates reproducible weighing and solution preparation. Store at −20 °C under appropriate laboratory conditions to maintain integrity. The one-gram unit balances economy with practical bench use for method set-up, calibration, and small-series experiments in chemical and life-science environments focused on ascorbic acid derivatives.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/acids\"\u003eAcids\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/collections\/acids-and-bases\"\u003eAcids \u0026amp; bases\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eColour: white to light yellow to light brown\u003c\/li\u003e\n\u003cli\u003eForm: powder\u003c\/li\u003e\n\u003cli\u003eAssay (titr.): ≥97 %\u003c\/li\u003e\n\u003cli\u003eIR-spectrum: complies\u003c\/li\u003e\n\u003cli\u003eCAS number: 490-83-5\u003c\/li\u003e\n\u003cli\u003ePack sizes: 1 g, 2 g, 5 g, 10 g\u003c\/li\u003e\n\u003cli\u003ePurity: min. 95 %\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₆H₆O₆\u003c\/li\u003e\n\u003cli\u003eStorage temperature: −20 °C\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-303C-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMzM3OXxhcHBsaWNhdGlvbi9wZGZ8YUdWaEwyaGtOQzg1TWpVME56ZzROemt5TXpVd0wxTlFSVnBmTXpBelExOUZUaTV3WkdZfGQ0ODEzMGM4ZmVkM2I5MjllYzE4YWQyYmZiYWNmOWM1YTA5ODQyNGZhMDUzZTEzN2ViNTU4NjEwODIwODQ0ZWY\" 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-303C-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyNDQ3ODN8YXBwbGljYXRpb24vcGRmfGFEaGhMMmhoTkM4NU1qSXhPRFV3Tmprek5qWXlMMU5FUWw4ek1ETkRYMFJGWDBWT0xuQmtaZ3xhOTRhNGZkNjI2Y2E4NWFkNDQ2MWMxNWI5NTBkYzQ4MzNiYmYwODg4Y2RmNDA4OGJlYWI3ZTEwMWZjYWJkOTI3\" 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":56148367901004,"sku":"303C.2","price":478.4,"currency_code":"EUR","in_stock":true},{"title":"1 g \/ 6+ pieces","offer_id":56148367933772,"sku":"303C.2","price":454.48,"currency_code":"EUR","in_stock":true},{"title":"1 g \/ 24+ pieces","offer_id":56148367966540,"sku":"303C.2","price":430.56,"currency_code":"EUR","in_stock":true},{"title":"2 g \/ 1 piece","offer_id":56148367999308,"sku":"303C.3","price":704.15,"currency_code":"EUR","in_stock":true},{"title":"2 g \/ 6+ pieces","offer_id":56148368032076,"sku":"303C.3","price":668.94,"currency_code":"EUR","in_stock":true},{"title":"2 g \/ 24+ pieces","offer_id":56148368064844,"sku":"303C.3","price":633.74,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 1 piece","offer_id":56148368097612,"sku":"303C.4","price":1306.15,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 6+ pieces","offer_id":56148368130380,"sku":"303C.4","price":1240.84,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 24+ pieces","offer_id":56148368163148,"sku":"303C.4","price":1175.54,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 1 piece","offer_id":56148368195916,"sku":"303C.5","price":1929.65,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 6+ pieces","offer_id":56148368228684,"sku":"303C.5","price":1833.17,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 24+ pieces","offer_id":56148368261452,"sku":"303C.5","price":1736.69,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-303C-SF.jpg?v=1766431844","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/l-dehydroascorbic-acid-303c-303c","provider":"Luminix Health","version":"1.0","type":"link"}
