{"product_id":"7-deaza-7-ethynyl-2-deoxyadenosine-3hht-3hht","title":"7-Deaza-7-ethynyl-2'-deoxyadenosine","description":"\u003cp\u003e7-Deaza-7-ethynyl-2'-deoxyadenosine is a modified deoxynucleoside supplied at a minimum purity of 95% for chemical-biology and nucleic-acid research. Its empirical formula is C₁₃H₁₄N₄O₃ and the molar mass is 274,28 g\/mol. The 7-deaza scaffold combined with a 7-ethynyl substituent introduces a bioorthogonal alkyne handle while altering base-pairing and stacking behaviour relative to natural 2'-deoxyadenosine. The product is packed as 5 mg in plastic, a practical quantity for oligonucleotide synthesis, click-labelling studies and structure–function investigations of modified DNA. The ethynyl group enables copper-catalysed or strain-promoted azide–alkyne cycloaddition, supporting attachment of fluorophores, biotin or other reporter groups after incorporation. Available from manufacturer Carl ROTH, this building block serves laboratories that require characterised nucleoside analogues with clear molecular specifications. Defined purity and molar mass assist accurate weighing and reaction stoichiometry. The small unit size suits method development, pilot conjugations and specialised applications in probe design and epigenetic or biophysical research without surplus inventory.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-nl\/collections\/coenzymes-nucleotides-and-vitamins\"\u003eCoenzymes, nucleotides \u0026amp; vitamins\u003c\/a\u003e, in \u003ca href=\"\/en-nl\/collections\/biochemicals-and-reagents\"\u003eBiochemicals \u0026amp; reagents\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAppearance: white to yellow solid\u003c\/li\u003e\n\u003cli\u003ePurity (HPLC): ≥95 %\u003c\/li\u003e\n\u003cli\u003ePack size: 5 mg plastic\u003c\/li\u003e\n\u003cli\u003ePurity: min. 95%\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₁₃H₁₄N₄O₃\u003c\/li\u003e\n\u003cli\u003eMolar mass: 274,28 g\/mol\u003c\/li\u003e\n\u003cli\u003eForm: plastic pack\u003c\/li\u003e\n\u003cli\u003eUNSPSC: 12352208\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-3HHT-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMjIyMnxhcHBsaWNhdGlvbi9wZGZ8YURnM0wyaG1aaTg1TWpVME9EVXhOemN5TkRRMkwxTlFSVnBmTTBoSVZGOUZUaTV3WkdZfDE4NTY3MTA0Mjc4YmJkMjA2NWZkYmI1MjEzY2NmN2FmMDhkOTFmMDJlMGRkM2IxNDY5YTBjNDBjNGY0YmQ5M2Y\" 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-3HHT-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyMzc4NjB8YXBwbGljYXRpb24vcGRmfGFEQTJMMmhrT0M4NU1qSTVORFV5T0RZNU5qWXlMMU5FUWw4elNFaFVYMFJGWDBWT0xuQmtaZ3xiODczYjg1Y2JjN2RhMjk4NTg0ZmJkMTJlZmE0NzViNWQ2NTQ4NmI4YjY0YzJlZWMyZDA5Y2Y1MjJhNTllM2Y4\" 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":"5 mg","offer_id":58952060895564,"sku":"3HHT.1","price":1101.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/3HHT-1.jpg?v=1790399031","url":"https:\/\/www.luminixhealth.com\/en-nl\/products\/7-deaza-7-ethynyl-2-deoxyadenosine-3hht-3hht","provider":"Luminix Health","version":"1.0","type":"link"}
