{"product_id":"l-arginine-ethyl-ester-dihydrochloride-2cxe-2cxe","title":"L-Arginine ethyl ester dihydrochloride, 50 g","description":"\u003cp\u003eL-Arginine ethyl ester dihydrochloride is an ethyl-ester derivative of L-arginine supplied as the dihydrochloride salt for laboratory synthesis and biochemical applications. It is registered under CAS number 36589-29-4, with the empirical formula C₈H₁₈N₄O₂·2HCl and a molar mass of 275,18 g\/mol. quantity is suited to peptide coupling trials, intermediate preparation and structure–activity exploration in medicinal and organic chemistry. Esterification of the carboxyl group modifies polarity and reactivity relative to free arginine, supporting controlled incorporation into peptide chains, prodrug concepts and arginine-analogue libraries. This reagent from manufacturer Carl ROTH is intended for research environments that require a defined L-arginine ethyl ester salt with transparent identity data. Consistent molecular characterisation aids documentation, batch tracking and reproducible use in synthetic workflows, screening campaigns and academic investigations focused on arginine chemistry.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/fr-fr\/collections\/click-chemistry-bioconjugation-and-synthesis-reagents\"\u003eClick chemistry, bioconjugation \u0026amp; synthesis reagents\u003c\/a\u003e, in \u003ca href=\"\/fr-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\u003eColour: white to yellow\u003c\/li\u003e\n\u003cli\u003eForm: powder\u003c\/li\u003e\n\u003cli\u003e¹H-NMR Spectrum: corresponds to assigned structure\u003c\/li\u003e\n\u003cli\u003ePurity (NMR): ≥ 95 %\u003c\/li\u003e\n\u003cli\u003eCAS number: 36589-29-4\u003c\/li\u003e\n\u003cli\u003ePack sizes: 50 g, 100 g, 250 g, 500 g\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₈H₁₈N₄O₂·2HCl\u003c\/li\u003e\n\u003cli\u003eMolar mass: 275,18 g\/mol\u003c\/li\u003e\n\u003cli\u003eStorage temperature: −20 °C\u003c\/li\u003e\n\u003cli\u003eProduct type: Biochemical reagent\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2CXE-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMzEyOHxhcHBsaWNhdGlvbi9wZGZ8YURjMEwyZ3daUzg1TWpVME5qWTNOVEUzT1RneUwxTlFSVnBmTWtOWVJWOUZUaTV3WkdZfGY1MjExZmRmZjY4Nzc4NGQyMjI4YTJmNzZmYzc2YjA0ZmVkZGY5YWY4YTYzNGZlNGU4NzUzNWE3NmQwN2I2ZGI\" 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-2CXE-DE-DE.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3w3ODY1MHxhcHBsaWNhdGlvbi9wZGZ8YURGakwyZ3lNaTg1TVRrMk1EazNOelkxTkRBMkwxTkVRbDh5UTFoRlgwUkZYMFJGTG5Ca1pnfDdkOTFiMjczZTAwZTEyOTI4MzYwZWNiNmUxYTc3Y2Q2ZTE5ZTQwNGIwNzVjYWYxZTgwYTEyOWUxNDgxNDMxMGI\" 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":"50 g \/ 1 piece","offer_id":56133007049036,"sku":"2CXE.2","price":241.9,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 6+ pieces","offer_id":56133007081804,"sku":"2CXE.2","price":229.81,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 24+ pieces","offer_id":56133007114572,"sku":"2CXE.2","price":217.71,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 1 piece","offer_id":56133007147340,"sku":"2CXE.3","price":407.45,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 6+ pieces","offer_id":56133007180108,"sku":"2CXE.3","price":387.08,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 24+ pieces","offer_id":56133007212876,"sku":"2CXE.3","price":366.71,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 1 piece","offer_id":56133007245644,"sku":"2CXE.4","price":858.95,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 6+ pieces","offer_id":56133007278412,"sku":"2CXE.4","price":816.0,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 24+ pieces","offer_id":56133007311180,"sku":"2CXE.4","price":773.06,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 1 piece","offer_id":56133007343948,"sku":"2CXE.5","price":1460.95,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 6+ pieces","offer_id":56133007376716,"sku":"2CXE.5","price":1387.9,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 24+ pieces","offer_id":56133007409484,"sku":"2CXE.5","price":1314.86,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2CXE-SF_a5c58143-c7af-4950-93fd-06d1636685dd.jpg?v=1766416633","url":"https:\/\/www.luminixhealth.com\/fr-fr\/products\/l-arginine-ethyl-ester-dihydrochloride-2cxe-2cxe","provider":"Luminix Health","version":"1.0","type":"link"}
