{"product_id":"fmoc-o-phospho-l-tyrosine-2ly2-2ly2","title":"Fmoc-O-phospho-L-tyrosine, min. 95 %, 500 mg","description":"\u003cp\u003eFmoc-O-phospho-L-tyrosine is an Fmoc-protected phosphotyrosine derivative for peptide synthesis, offered at a minimum purity of 95 %. It carries CAS number 147762-53-6, empirical formula C₂₄H₂₂NO₈P and a molar mass of 483,41 g\/mol. The free O-phospho group on the tyrosine side chain allows direct introduction of a phosphorylated aromatic residue into Fmoc-based solid-phase sequences used in cell-signalling, antibody-epitope and kinase-substrate research. Biochemists and medicinal chemists can employ it to prepare site-specifically phosphorylated peptides for binding assays, mass-spectrometric standards and structure–function studies. Integration into standard Fmoc protocols supports reproducible access to phospho-tyrosine containing sequences without multi-step post-assembly phosphorylation. Use under established laboratory conditions for protected amino acids and organophosphate building blocks.\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\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: 147762-53-6\u003c\/li\u003e\n\u003cli\u003ePack sizes: 500 mg, 1 g, 2 g\u003c\/li\u003e\n\u003cli\u003ePurity: min. 95 %\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₂₄H₂₂NO₈P\u003c\/li\u003e\n\u003cli\u003eStorage temperature: -20 °C\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2LY2-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwNjA4MHxhcHBsaWNhdGlvbi9wZGZ8YURkaUwyaGxZUzg1TWpVME56RTNPREUyT0RZeUwxTlFSVnBmTWt4Wk1sOUZUaTV3WkdZfDAzMmM4MGFiYzA1ZTUwYjcyODYyYzA5MjI0MGUwZWY4YWFkYmE0OWM0MTc4N2Y0ZTEzM2I1ZjRlODhiMTY3YjU\" 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-2LY2-DE-DE.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3w3ODY1MHxhcHBsaWNhdGlvbi9wZGZ8YURVeUwyZzJaQzg1TVRrMk1qQTJORGc1TmpNd0wxTkVRbDh5VEZreVgwUkZYMFJGTG5Ca1pnfGQ0NTM5MjQyNmUwNjE2ZTI5ZjI3YmM1YjZlY2M3OGIwMjhiZDUzZTM4MjA0ZDYyMzI1NWQyNDk2YmE3YjUzNWU\" 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":"500 mg \/ 1 piece","offer_id":56141199278412,"sku":"2LY2.3","price":241.9,"currency_code":"EUR","in_stock":true},{"title":"500 mg \/ 6+ pieces","offer_id":56141199311180,"sku":"2LY2.3","price":229.81,"currency_code":"EUR","in_stock":true},{"title":"500 mg \/ 24+ pieces","offer_id":56141199343948,"sku":"2LY2.3","price":217.71,"currency_code":"EUR","in_stock":true},{"title":"1 g \/ 1 piece","offer_id":56141199376716,"sku":"2LY2.4","price":385.95,"currency_code":"EUR","in_stock":true},{"title":"1 g \/ 6+ pieces","offer_id":56141199409484,"sku":"2LY2.4","price":385.95,"currency_code":"EUR","in_stock":true},{"title":"1 g \/ 24+ pieces","offer_id":56141199442252,"sku":"2LY2.4","price":385.95,"currency_code":"EUR","in_stock":true},{"title":"2 g \/ 1 piece","offer_id":56141199475020,"sku":"2LY2.5","price":478.4,"currency_code":"EUR","in_stock":true},{"title":"2 g \/ 6+ pieces","offer_id":56141199507788,"sku":"2LY2.5","price":454.48,"currency_code":"EUR","in_stock":true},{"title":"2 g \/ 24+ pieces","offer_id":56141199540556,"sku":"2LY2.5","price":430.56,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2LY2-SF_9c2e55dc-3bf8-4709-90cf-2cbe6f1570f8.jpg?v=1766418271","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/fmoc-o-phospho-l-tyrosine-2ly2-2ly2","provider":"Luminix Health","version":"1.0","type":"link"}
