{"product_id":"s-benzyl-l-cysteine-2enc-2enc","title":"S-Benzyl-L-cysteine, min. 95 %, 50 g","description":"\u003cp\u003eS-Benzyl-L-cysteine, min. 95 %, is a side-chain-protected L-cysteine derivative widely applied in peptide chemistry and sulphur-containing amino-acid research. Identified by CAS number 3054-01-1 and empirical formula C₁₀H₁₃NO₂S, it has a molar mass of 211,28 g\/mol, a flash point of 183,2 °C and a boiling point of 379,2 °C. provides a practical quantity for laboratory synthesis of cysteine-rich peptides, thiol-protection studies and intermediate preparation. This material from manufacturer Carl ROTH supports workflows that require temporary S-benzyl protection prior to selective deprotection. Its defined purity grade and physicochemical profile aid reproducible coupling, purification and analytical characterisation. Organic and biochemical laboratories can use the reagent in solid-phase peptide synthesis, medicinal chemistry programmes and the construction of modified peptides. Documented CAS, formula and thermal data simplify material handling, safety assessment and batch documentation within regulated research environments.\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\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCAS number: 3054-01-1\u003c\/li\u003e\n\u003cli\u003ePack sizes: 50 g, 100 g, 250 g\u003c\/li\u003e\n\u003cli\u003ePurity: min. 95 %\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₁₀H₁₃NO₂S\u003c\/li\u003e\n\u003cli\u003eMolar mass: 211,28 g\/mol\u003c\/li\u003e\n\u003cli\u003eFlash point: 183,2 °C\u003c\/li\u003e\n\u003cli\u003eBoiling point: 379,2 °C\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2ENC-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMjc5NnxhcHBsaWNhdGlvbi9wZGZ8YUdOaEwyZzJOeTg1TWpVME5qYzVOakE1TXpjMEwxTlFSVnBmTWtWT1ExOUZUaTV3WkdZfDA0NjBmYjI4Y2M1N2NkZDM4OWZmNmQ2NzJjZThlMDBhZTdkZDlmYmZkMDQ4ZWNiNmY5NDViNTAxMGNkZWFkNDc\" 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\u003c\/ul\u003e","brand":"Carl Roth","offers":[{"title":"50 g \/ 1 piece","offer_id":56134050971980,"sku":"2ENC.1","price":106.45,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 6+ pieces","offer_id":56134051004748,"sku":"2ENC.1","price":101.13,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 24+ pieces","offer_id":56134051037516,"sku":"2ENC.1","price":95.81,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 1 piece","offer_id":56134051070284,"sku":"2ENC.2","price":117.2,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 6+ pieces","offer_id":56134051103052,"sku":"2ENC.2","price":111.34,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 24+ pieces","offer_id":56134051135820,"sku":"2ENC.2","price":105.48,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 1 piece","offer_id":56134051168588,"sku":"2ENC.3","price":263.4,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 6+ pieces","offer_id":56134051201356,"sku":"2ENC.3","price":250.23,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 24+ pieces","offer_id":56134051234124,"sku":"2ENC.3","price":237.06,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2ENC-SF_f338eab6-8575-4d62-ac0a-5399fbe3881b.jpg?v=1766417047","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/s-benzyl-l-cysteine-2enc-2enc","provider":"Luminix Health","version":"1.0","type":"link"}
