{"product_id":"d-valine-ethyl-ester-hydrochloride-2y3a-2y3a","title":"D-Valine ethyl ester hydrochloride, min. 95 %, 10 g","description":"\u003cp\u003eD-Valine ethyl ester hydrochloride is a compact protected amino-acid derivative offered at min. 95 % purity for peptide chemistry and chiral synthesis. It is identified by CAS number 73913-64-1, the empirical formula C₇H₁₅NO₂·HCl and a molar mass of 181,66 g\/mol. The ethyl ester provides a readily cleavable carboxyl protection, while the hydrochloride salt form aids handling and accurate dosing. D-Valine building blocks are employed to introduce non-natural stereochemistry into peptides, to modulate proteolytic stability and to construct stereochemically defined intermediates. Clear specification of molar mass, CAS number and minimum purity supports stoichiometric planning and quality documentation. The reagent integrates smoothly into standard solution-phase and solid-phase protocols used in academic and industrial biochemical laboratories.\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\u003ePurity (GC): reported (%)\u003c\/li\u003e\n\u003cli\u003ePurity (HPLC): reported (%)\u003c\/li\u003e\n\u003cli\u003eIR-spectrum: corresponds to reference spectrum\u003c\/li\u003e\n\u003cli\u003epH value: reported ()\u003c\/li\u003e\n\u003cli\u003eAssay (TLC): reported (%)\u003c\/li\u003e\n\u003cli\u003eContent (acidim.): reported (%)\u003c\/li\u003e\n\u003cli\u003eAssay: reported (%)\u003c\/li\u003e\n\u003cli\u003eMelting point: reported (°C)\u003c\/li\u003e\n\u003cli\u003eColour: reported\u003c\/li\u003e\n\u003cli\u003eForm: reported\u003c\/li\u003e\n\u003cli\u003eCAS number: 73913-64-1\u003c\/li\u003e\n\u003cli\u003ePack sizes: 10 g, 25 g, 50 g, 100 g\u003c\/li\u003e\n\u003cli\u003ePurity: min. 95 %\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₇H₁₅NO₂·HCl\u003c\/li\u003e\n\u003cli\u003eMolar mass: 181,66 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-2Y3A-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwNjI1OXxhcHBsaWNhdGlvbi9wZGZ8YUdFeUwyZzRaQzg1TWpVME56YzJNVEV4TVRNMEwxTlFSVnBmTWxrelFWOUZUaTV3WkdZfDliMWVhNzk2OWE5YzcxYTNhYWNjMTEyNzNjNjllNjg5MTQyY2Q1ZWZlOTNiMzdkMTE0MjEzNDc0ZWZiMDg0OGE\" 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-2Y3A-DE-DE.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3w3ODY1MHxhcHBsaWNhdGlvbi9wZGZ8YURJNEwyZ3dPQzg1TVRrMk16SXpORGN4TXprd0wxTkVRbDh5V1ROQlgwUkZYMFJGTG5Ca1pnfDgwMzU2NWMyYzYyNTI2OThiZDIwMjMxMGQ1YjdkZjc1ODkzMjYxYjUxNzBlOTg5OGIxMjU1NzdiMzQ1MDExYTk\" 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":"10 g \/ 1 piece","offer_id":56148153991500,"sku":"2Y3A.2","price":203.2,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 6+ pieces","offer_id":56148154024268,"sku":"2Y3A.2","price":193.04,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 24+ pieces","offer_id":56148154057036,"sku":"2Y3A.2","price":182.88,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 1 piece","offer_id":56148154089804,"sku":"2Y3A.3","price":403.15,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 6+ pieces","offer_id":56148154122572,"sku":"2Y3A.3","price":382.99,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 24+ pieces","offer_id":56148154155340,"sku":"2Y3A.3","price":362.84,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 1 piece","offer_id":56148154188108,"sku":"2Y3A.4","price":704.15,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 6+ pieces","offer_id":56148154220876,"sku":"2Y3A.4","price":668.94,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 24+ pieces","offer_id":56148154253644,"sku":"2Y3A.4","price":633.74,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 1 piece","offer_id":56148154286412,"sku":"2Y3A.5","price":1198.65,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 6+ pieces","offer_id":56148154319180,"sku":"2Y3A.5","price":1138.72,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 24+ pieces","offer_id":56148154351948,"sku":"2Y3A.5","price":1078.79,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2Y3A-SF_a3a739a9-af3f-4f48-86f3-ab9e8d6c3d21.jpg?v=1766419998","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/d-valine-ethyl-ester-hydrochloride-2y3a-2y3a","provider":"Luminix Health","version":"1.0","type":"link"}
