{"product_id":"fmoc-l-tryptophan-peptipure-6903","title":"Fmoc-L-Tryptophan, PEPTIPURE®, min. 98 %, for biochemistry, 5 g, glass","description":"\u003cp\u003eFmoc-L-Tryptophan, PEPTIPURE® is an Nα-Fmoc-protected L-tryptophan building block offered at a minimum purity of 98 % for biochemistry and peptide synthesis. It carries CAS number 35737-15-6, the empirical formula C₂₆H₂₂N₂O₄ and a molar mass of 426,46 g\/mol. The Fmoc group shields the α-amino function during stepwise assembly and is removed under mild basic conditions, allowing controlled incorporation of the indole-containing tryptophan residue into synthetic peptides. This PEPTIPURE® quality material supports solid-phase and solution-phase Fmoc strategies, sequence optimisation and laboratory-scale peptide production where defined purity and L-configuration are essential. Laboratories can apply this protected amino acid within standard Fmoc coupling chemistry without changing established deprotection or activation protocols.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/click-chemistry-bioconjugation-and-synthesis-reagents\"\u003eClick chemistry, bioconjugation \u0026amp; synthesis reagents\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/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 powder\u003c\/li\u003e\n\u003cli\u003eAssay: ≥98,0 %\u003c\/li\u003e\n\u003cli\u003eWater (KF): ≤1,0 %\u003c\/li\u003e\n\u003cli\u003eCAS number: 35737-15-6\u003c\/li\u003e\n\u003cli\u003ePack sizes: 5 g, 25 g, 100 g\u003c\/li\u003e\n\u003cli\u003eEG nr.: 252-706-5\u003c\/li\u003e\n\u003cli\u003ePurity: min. 98 %\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₂₆H₂₂N₂O₄\u003c\/li\u003e\n\u003cli\u003eMolar mass: 426,46 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-6903-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwNDc4MnxhcHBsaWNhdGlvbi9wZGZ8YURNMUwyZzBOeTg1TWpVME9URXpOak00TkRNd0wxTlFSVnBmTmprd00xOUZUaTV3WkdZfGVmYmM1ZDI4ZTVjNzQwN2YyNzI2MmQ0OTM3OTA5MGQ0ZGY2MTY1MGE3MzRiN2Y0NWZlYWY2ZTg5MWFmYWZmMjg\" 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-6903-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyMzg1MjZ8YXBwbGljYXRpb24vcGRmfGFEVm1MMmhtWmk4NU1qQTJOell5TWpReU1EYzRMMU5FUWw4Mk9UQXpYMFJGWDBWT0xuQmtaZ3wwMWM4ZGNhMzgyYWViZDEzZjdiYzcxMTQ1ZTQ3NzEwNTY0MTllMTJmNmZiNzU4YWM4ZWM0OTFlNGY3OWVjMWQz\" 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 g \/ 1 piece","offer_id":56173010878796,"sku":"6903.1","price":23.15,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 6+ pieces","offer_id":56173010911564,"sku":"6903.1","price":21.99,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 24+ pieces","offer_id":56173010944332,"sku":"6903.1","price":20.84,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 1 piece","offer_id":56173010977100,"sku":"6903.2","price":73.0,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 6+ pieces","offer_id":56173011009868,"sku":"6903.2","price":69.35,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 24+ pieces","offer_id":56173011042636,"sku":"6903.2","price":65.7,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 1 piece","offer_id":56173011075404,"sku":"6903.3","price":231.15,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 6+ pieces","offer_id":56173011108172,"sku":"6903.3","price":219.59,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 24+ pieces","offer_id":56173011140940,"sku":"6903.3","price":208.04,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/6903-SF-1000Wx1000H_a8e8bcf4-9e0c-4596-9c77-84c5d8a49b17.jpg?v=1766442604","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/fmoc-l-tryptophan-peptipure-6903","provider":"Luminix Health","version":"1.0","type":"link"}
