{"product_id":"o-methyl-l-threonine-2pkp-2pkp","title":"O-Methyl-L-threonine, min. 95 %, 5 g","description":"\u003cp\u003eO-Methyl-L-threonine is a protected threonine derivative offered at a minimum purity of 95 % for laboratory and biochemical applications. It is identified by CAS number 4144-02-9, with the empirical formula C₅H₁₁NO₃ and a molar mass of 133,15 g\/mol. These identity parameters support accurate documentation in research notebooks, electronic lab systems, and purchasing records. The compound is Chemists and biochemists developing modified peptides, unnatural amino acid libraries, or specialised intermediates can use this grade in exploratory and scale-up experiments. The material is available from manufacturer Carl ROTH within its biochemicals assortment and is intended for professional laboratory use only. O-methylation on the threonine side chain alters hydrogen-bonding and polarity relative to native threonine, a modification frequently examined in medicinal chemistry and peptide design. Stated purity, CAS number, empirical formula, and molar mass help laboratories maintain consistent specifications across batches and projects. Handle the solid according to institutional chemical safety procedures and the information supplied with the product packaging.\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\u003eAssay: ≥ 95 %\u003c\/li\u003e\n\u003cli\u003eColour: reported\u003c\/li\u003e\n\u003cli\u003eForm: reported\u003c\/li\u003e\n\u003cli\u003eCAS number: 4144-02-9\u003c\/li\u003e\n\u003cli\u003ePack sizes: 5 g, 10 g\u003c\/li\u003e\n\u003cli\u003ePurity: min. 95 %\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₅H₁₁NO₃\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2PKP-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMjQ4M3xhcHBsaWNhdGlvbi9wZGZ8YUdabUwyZzVOUzg1TWpVME56UXlOVFUyTnpBeUwxTlFSVnBmTWxCTFVGOUZUaTV3WkdZfGZjNzZiOTE4OWNkZjFhMzM1ZDNhYWY3YTBlMjNkZGQyOWExYTFjYTA4ZDRmMjY5ZTYzNzU2ZWQzNzU2NWY0OTY\" 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-2PKP-DE-DE.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3w3ODY1MHxhcHBsaWNhdGlvbi9wZGZ8YURZMEwyZzNOUzg1TVRrMk1qVTJNamsyT1Rrd0wxTkVRbDh5VUV0UVgwUkZYMFJGTG5Ca1pnfGE2MDg1YTBiMTU0MDAwOWQxOTYwMDg0OTI3OTg2M2Y3MDYxNDcyNjVlMjAyMTU3ZTcxYTIzYzQwMjRhM2JjY2E\" 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":"5 g \/ 1 piece","offer_id":56146179457356,"sku":"2PKP.4","price":450.45,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 6+ pieces","offer_id":56146179490124,"sku":"2PKP.4","price":427.93,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 24+ pieces","offer_id":56146179522892,"sku":"2PKP.4","price":405.41,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 1 piece","offer_id":56146179555660,"sku":"2PKP.5","price":289.2,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 6+ pieces","offer_id":56146179588428,"sku":"2PKP.5","price":274.74,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 24+ pieces","offer_id":56146179621196,"sku":"2PKP.5","price":260.28,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2PKP-SF_140def0c-16ee-4c9b-8224-701139faf51c.jpg?v=1766419096","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/o-methyl-l-threonine-2pkp-2pkp","provider":"Luminix Health","version":"1.0","type":"link"}
