{"product_id":"l-theanine-2xk7-2xk7","title":"L-Theanine, 50 g","description":"\u003cp\u003eL-Theanine is a non-proteinogenic amino acid with the empirical formula C₇H₁₄N₂O₃, CAS number 3081-61-6 and a molar mass of 174,2 g\/mol. The compound shows a boiling point of 430,2 °C and is widely recognised as the characteristic amino acid of tea leaves, making it relevant for studies of amino-acid metabolism, neurochemistry and natural-product characterisation. Laboratories select L-theanine when preparing reference solutions, formulating experimental media or examining structure–activity relationships of glutamine analogues. Material from manufacturer Carl ROTH provides a clearly specified identity and pack size that support routine weighing and documentation.\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\u003eColour: white to off-white\u003c\/li\u003e\n\u003cli\u003eForm: powder\u003c\/li\u003e\n\u003cli\u003ePurity (HPLC): ≥98 %\u003c\/li\u003e\n\u003cli\u003e¹H-NMR Spectrum: complies\u003c\/li\u003e\n\u003cli\u003eCAS number: 3081-61-6\u003c\/li\u003e\n\u003cli\u003ePack sizes: 50 g, 100 g, 250 g\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₇H₁₄N₂O₃\u003c\/li\u003e\n\u003cli\u003eMolar mass: 174,2 g\/mol\u003c\/li\u003e\n\u003cli\u003eBoiling point: 430,2 °C\u003c\/li\u003e\n\u003cli\u003eStorage temperature: +2 to +8 °C\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2XK7-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMzEwNHxhcHBsaWNhdGlvbi9wZGZ8YURRd0wyZ3hOQzg1TWpneU5qa3lNRGczT0RNNEwxTlFSVnBmTWxoTE4xOUZUaTV3WkdZfGQ2YjdkNzA0NzJkNTYxNGEzNDFhNTgxZTQ1ZmNhZThlNjkyOTc5ODU4OWY5YTNmNTQxYmIyZmRmOWMxNGFlZGU\" 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-2XK7-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyNDQ5MDJ8YXBwbGljYXRpb24vcGRmfGFETTBMMmc1T1M4NU1qYzBNRGM0T1RJd056TTBMMU5FUWw4eVdFczNYMFJGWDBWT0xuQmtaZ3xiMjkxMTM1NzZhNDAyNzk1N2ZjZmExNGVkZDJkNWZjMWQyYjNmOTA3MzIzMWRlMmEwMTJiMWU2OWM4MDYyZWU0\" 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":56148072530252,"sku":"2XK7.3","price":256.95,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 6+ pieces","offer_id":56148072563020,"sku":"2XK7.3","price":244.1,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 24+ pieces","offer_id":56148072595788,"sku":"2XK7.3","price":231.26,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 1 piece","offer_id":56148072628556,"sku":"2XK7.4","price":353.7,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 6+ pieces","offer_id":56148072661324,"sku":"2XK7.4","price":336.02,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 24+ pieces","offer_id":56148072694092,"sku":"2XK7.4","price":318.33,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 1 piece","offer_id":56148072726860,"sku":"2XK7.5","price":489.15,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 6+ pieces","offer_id":56148072759628,"sku":"2XK7.5","price":464.69,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 24+ pieces","offer_id":56148072792396,"sku":"2XK7.5","price":440.24,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2XK7-SF_33e984f9-684f-487a-8e6d-a68002f014d9.jpg?v=1766419860","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/l-theanine-2xk7-2xk7","provider":"Luminix Health","version":"1.0","type":"link"}
