{"product_id":"fmoc-12-aminododecanoic-acid-2ly4-2ly4","title":"Fmoc-12-aminododecanoic acid, min. 95 %, 2 g","description":"\u003cp\u003eFmoc-12-aminododecanoic acid is a long-chain Fmoc-protected ω-amino acid building block offered at a minimum purity of 95 %. It is defined by CAS number 128917-74-8, empirical formula C₂₇H₃₅NO₄ and a molar mass of 437,57 g\/mol. The twelve-carbon spacer between the Fmoc-protected amine and the carboxylic acid makes it a versatile linker and spacer unit for solid-phase peptide synthesis, conjugate design and surface or resin functionalisation. Applications include distance control between epitopes, attachment of reporter groups and construction of lipophilic peptide analogues. The Fmoc handle enables compatibility with standard Fmoc\/tBu protocols, while the terminal carboxylic acid couples under conventional activation conditions. Intended for research laboratories requiring a defined aminododecanoic acid derivative with clear chemical identity for reproducible synthetic workflows.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/acids\"\u003eAcids\u003c\/a\u003e, in \u003ca href=\"\/en-be\/collections\/acids-and-bases\"\u003eAcids \u0026amp; bases\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCAS number: 128917-74-8\u003c\/li\u003e\n\u003cli\u003ePack sizes: 2 g, 5 g, 10 g, 25 g\u003c\/li\u003e\n\u003cli\u003ePurity: min. 95 %\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₂₇H₃₅NO₄\u003c\/li\u003e\n\u003cli\u003eMolar mass: 437,57 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-2LY4-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMzA5NnxhcHBsaWNhdGlvbi9wZGZ8YUdVeEwyaG1NQzg1TWpVME56RTNOalV6TURJeUwxTlFSVnBmTWt4Wk5GOUZUaTV3WkdZfGM0MGQxMTg5NmI4NzAzN2UyMzUxNDhlNDRjMjg1NzI0ZWUzYzhjODM5NzM4YjNlYjVjZmE3NTU5ZjI2Yzk3NzM\" 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":"2 g \/ 1 piece","offer_id":56141199901004,"sku":"2LY4.2","price":256.95,"currency_code":"EUR","in_stock":true},{"title":"2 g \/ 6+ pieces","offer_id":56141199933772,"sku":"2LY4.2","price":244.1,"currency_code":"EUR","in_stock":true},{"title":"2 g \/ 24+ pieces","offer_id":56141199966540,"sku":"2LY4.2","price":231.26,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 1 piece","offer_id":56141199999308,"sku":"2LY4.3","price":611.7,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 6+ pieces","offer_id":56141200032076,"sku":"2LY4.3","price":581.12,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 24+ pieces","offer_id":56141200064844,"sku":"2LY4.3","price":550.53,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 1 piece","offer_id":56141200097612,"sku":"2LY4.4","price":955.7,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 6+ pieces","offer_id":56141200130380,"sku":"2LY4.4","price":907.92,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 24+ pieces","offer_id":56141200163148,"sku":"2LY4.4","price":860.13,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 1 piece","offer_id":56141200195916,"sku":"2LY4.5","price":719.2,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 6+ pieces","offer_id":56141200228684,"sku":"2LY4.5","price":683.24,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 24+ pieces","offer_id":56141200261452,"sku":"2LY4.5","price":647.28,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2LY4-SF_fe0ffaf7-513d-4c46-8f43-a57df2b32d1b.jpg?v=1766418271","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/fmoc-12-aminododecanoic-acid-2ly4-2ly4","provider":"Luminix Health","version":"1.0","type":"link"}
