{"product_id":"tert-butyl-1-piperazinecarboxylate-2e90","title":"tert-Butyl 1-piperazinecarboxylate","description":"\u003cp\u003etert-Butyl 1-piperazinecarboxylate is a Boc-protected piperazine derivative offered at a minimum purity of 95 % for laboratory synthesis and biochemical applications. The compound is registered under CAS number 57260-71-6 and corresponds to the empirical formula C₉H₁₈N₂O₂, with a molar mass of 186,25 g\/mol. These identity data support accurate dosing and documentation in research protocols. Supplied in a 5 kg pack, the material suits preparative work and repeated use in multi-step sequences where a temporary protecting group on piperazine is required. Catalogue material from manufacturer Carl ROTH provides a clearly specified grade that helps laboratories maintain consistent starting quality across batches. Typical contexts include medicinal chemistry, intermediate preparation and the assembly of more elaborate nitrogen heterocycles under controlled laboratory conditions. Clear CAS, formula and molar-mass information simplify inventory control, receiving checks and stoichiometric planning on the bench or in the kilo-lab. This biochemical reagent is intended for professional chemical and life-science laboratories that need a defined Boc-piperazine building block in a larger pack size for ongoing synthetic programmes.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/de-be\/collections\/organic-building-blocks-and-synthesis-reagents\"\u003eOrganic building blocks \u0026amp; synthesis reagents\u003c\/a\u003e, in \u003ca href=\"\/de-be\/collections\/organic-chemicals-and-synthesis-reagents\"\u003eOrganic chemicals \u0026amp; synthesis reagents\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMolar mass: 186,25 g\/mol\u003c\/li\u003e\n\u003cli\u003eUNSPSC: 12352200\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2E90-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMjc1MnxhcHBsaWNhdGlvbi9wZGZ8YUdNM0wyZzROUzg1TWpVME5qYzBNalk0TVRrd0wxTlFSVnBmTWtVNU1GOUZUaTV3WkdZfDU1NTNmZWIzNmMxYWY4MzIyMTQwNjlmZjQyNzU4MDdiMjdlMDQ0N2E3Y2NkZjdkZmIwZDhhZmZmMzI1MjVjNmY\" 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-2E90-DE-DE.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3w3ODY1MHxhcHBsaWNhdGlvbi9wZGZ8YURSbEwyZ3dNeTg1TVRrMk1URXhORFl5TkRNd0wxTkVRbDh5UlRrd1gwUkZYMFJGTG5Ca1pnfDkxZjQwNTQzOGE2MGNhMTgxYmNiY2YyNzQ5NjU0YzcwZjg0YTVjMjUwOWY0YjA0NWNiZmIxOTBlYzZhMjgyZGQ\" 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":"2 kg","offer_id":58952041824588,"sku":"2E90.5","price":875.05,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/2E90-5.jpg?v=1790398524","url":"https:\/\/www.luminixhealth.com\/de-be\/products\/tert-butyl-1-piperazinecarboxylate-2e90","provider":"Luminix Health","version":"1.0","type":"link"}
