It can promote the reaction between the carboxyl group of the activated amino acid and the amine group of the growing peptide chain without affecting the formation of the peptide bond. In addition, DIPEA can improve the deprotection of amino acid residues during peptide synthesis by scavenging acidic impurities.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\n\u003c!-- DeliveryText --\u003e\n\n\u003c!-- printCatalogLink --\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col-xs-12 col-md-6\" style=\"flex:0 0 55%; max-width:55%; box-sizing:border-box; margin:10px 0; margin-left:-3%; \"\u003e\n\u003cdiv class=\"product-classifications\"\u003e\n\u003cdiv class=\"headline\" style=\"font-weight:bold; font-size:1.2em; margin-bottom:10px;\"\u003eTechnical Information\u003c\/div\u003e\n\u003ctable class=\"table\" style=\"; table-layout:fixed; word-break:normal; overflow-wrap:break-word; width:100%;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"attrib\" style=\"padding:8px 6px; vertical-align:top; box-sizing:border-box; font-weight:bold; font-size:1em; white-space:normal; overflow-wrap:break-word; hyphens:auto; word-break:normal; \"\u003eAppearance\u003c\/td\u003e\n\u003ctd style=\"padding:8px 6px; vertical-align:top; box-sizing:border-box; font-size:0.92em; white-space:normal; word-break:normal; overflow-wrap:break-word; hyphens:auto; \"\u003e\n\t\t\t\t\t\t\t\t\tfarblos bis gelbliche, klare Flüssigkeit \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv style=\"margin-top:1.5rem;\"\u003e\n  \u003ca href=\"https:\/\/www.carlroth.com\/medias\/SPEZ-2474-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwNDYyNHxhcHBsaWNhdGlvbi9wZGZ8YURsa0wyZzFZUzg1TWpVME5UazROakEyT0RjNEwxTlFSVnBmTWpRM05GOUZUaTV3WkdZfDNmNjE5NDNjZjM3ZGRhNDlhNmRlNTA1ZDgxODM5M2FhYmVlMjlmYjAzOTU0MDE0NTg4OGNmMTQ0MDNkMjJkZTA\" target=\"_blank\" rel=\"noopener noreferrer\" download style=\"display:inline-flex; align-items:center; gap:.65rem; text-decoration:none; color:#000; font-weight:600; font-size:1rem;\"\u003e\n    \u003csvg style=\"width:1.65rem;height:1.65rem;color:#dc2626;flex-shrink:0;\" viewbox=\"0 0 384 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" aria-hidden=\"true\"\u003e\n      \u003cpath d=\"M64 0C28.7 0 0 28.7 0 64V448c0 35.3 28.7 64 64 64H320c35.3 0 64-28.7 64-64V160H256c-17.7 0-32-14.3-32-32V0H64z\" fill=\"#ffffff\" stroke=\"currentColor\" stroke-width=\"32\"\u003e\u003c\/path\u003e\n      \u003cpath d=\"M256 0V128H384L256 0z\" fill=\"currentColor\"\u003e\u003c\/path\u003e\n      \u003ctext x=\"192\" y=\"380\" font-family=\"Arial, Helvetica, sans-serif\" font-size=\"110\" font-weight=\"bold\" fill=\"currentColor\" text-anchor=\"middle\"\u003ePDF\u003c\/text\u003e\n    \u003c\/svg\u003e\n    Technical Documentation (PDF)\n  \u003c\/a\u003e\n\u003c\/div\u003e","brand":"Carl Roth","offers":[{"title":"100 ml \/ 1 piece","offer_id":56128330006860,"sku":"2474.1","price":35.4,"currency_code":"EUR","in_stock":true},{"title":"100 ml \/ 6+ pieces","offer_id":56128330039628,"sku":"2474.1","price":33.63,"currency_code":"EUR","in_stock":true},{"title":"100 ml \/ 24+ pieces","offer_id":56128330072396,"sku":"2474.1","price":31.86,"currency_code":"EUR","in_stock":true},{"title":"250 ml \/ 1 piece","offer_id":56128330105164,"sku":"2474.2","price":64.0,"currency_code":"EUR","in_stock":true},{"title":"250 ml \/ 6+ pieces","offer_id":56128330137932,"sku":"2474.2","price":60.8,"currency_code":"EUR","in_stock":true},{"title":"250 ml \/ 24+ pieces","offer_id":56128330170700,"sku":"2474.2","price":57.6,"currency_code":"EUR","in_stock":true},{"title":"1 liter \/ 1 piece","offer_id":56128330203468,"sku":"2474.3","price":213.95,"currency_code":"EUR","in_stock":true},{"title":"1 liter \/ 6+ pieces","offer_id":56128330236236,"sku":"2474.3","price":213.95,"currency_code":"EUR","in_stock":true},{"title":"1 liter \/ 24+ pieces","offer_id":56128330269004,"sku":"2474.3","price":213.95,"currency_code":"EUR","in_stock":true},{"title":"2.5 liter \/ 1 piece","offer_id":56128330301772,"sku":"2474.4","price":439.7,"currency_code":"EUR","in_stock":true},{"title":"2.5 liter \/ 6+ pieces","offer_id":56128330334540,"sku":"2474.4","price":417.72,"currency_code":"EUR","in_stock":true},{"title":"2.5 liter \/ 24+ pieces","offer_id":56128330367308,"sku":"2474.4","price":395.73,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/2474-1000Wx1000H_b84318ee-6022-4c0b-9e15-17cb23b17dc7.jpg?v=1766413766","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/n-n-diisopropylethylamine-peptipure-2474","provider":"Luminix Health","version":"1.0","type":"link"}
