The empirical formula is C₉H₁₁NO₂ and the molar mass is 171,15 g\/mol, consistent with six ¹³C atoms in the phenylalanine framework. This isotopically enriched reagent is In biochemical and analytical laboratories it supports metabolic flux studies, quantitative proteomics, NMR experiments and mass-spectrometry workflows where a stable-isotope standard or labelled precursor is required. The compound retains the chemical behaviour of native L-phenylalanine while providing a clear mass shift for detection and internal calibration. Available from manufacturer Carl ROTH, the material suits method development, calibration mixes and labelling schemes in cell culture, enzyme assays and structural biology. Defined identity, documented molar mass and convenient small-pack presentation help laboratories plan reproducible experiments with minimal material consumption across research and quality-control settings.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/click-chemistry-bioconjugation-and-synthesis-reagents\"\u003eClick chemistry, bioconjugation \u0026amp; synthesis reagents\u003c\/a\u003e, in \u003ca href=\"\/en-be\/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\u003eAssay: ≥ 95 %\u003c\/li\u003e\n\u003cli\u003eColour: reported\u003c\/li\u003e\n\u003cli\u003eForm: reported\u003c\/li\u003e\n\u003cli\u003eCAS number: 180268-82-0\u003c\/li\u003e\n\u003cli\u003ePack sizes: 2 mg, 5 mg, 10 mg, 25 mg\u003c\/li\u003e\n\u003cli\u003ePurity: min. 95 %\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₉H₁₁NO₂\u003c\/li\u003e\n\u003cli\u003eMolar mass: 171,15 g\/mol\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-2NLX-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMzQwM3xhcHBsaWNhdGlvbi9wZGZ8YURrM0wyZzFNaTg1TWpVME56STRPVEkxTWpFMEwxTlFSVnBmTWs1TVdGOUZUaTV3WkdZfGY2YTg5ZmUyOWJhOGU2NGMzNjMyMTY5NTU5NTFjZDdiOTA0ZjY2MDVjNjQxYTU3Yzc0MDA0YmYyNWExZmUwOGI\" 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-2NLX-DE-DE.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3w3ODY1MHxhcHBsaWNhdGlvbi9wZGZ8YURFM0wyaGlOaTg1TVRrMk1qSTVORFU1T1RrNEwxTkVRbDh5VGt4WVgwUkZYMFJGTG5Ca1pnfGRkMTFjMmJkOGUyMTgwMTk1ZWY1YTYzNjcwMmQwMWMwZTlkZWZiZjkyNDlhNDQ0ODBmNmY2YWI5NTAzYjcyNzY\" 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":"2 mg \/ 1 piece","offer_id":56145625973068,"sku":"2NLX.2","price":220.4,"currency_code":"EUR","in_stock":true},{"title":"2 mg \/ 6+ pieces","offer_id":56145626005836,"sku":"2NLX.2","price":209.38,"currency_code":"EUR","in_stock":true},{"title":"2 mg \/ 24+ pieces","offer_id":56145626038604,"sku":"2NLX.2","price":198.36,"currency_code":"EUR","in_stock":true},{"title":"5 mg \/ 1 piece","offer_id":56145626071372,"sku":"2NLX.3","price":349.4,"currency_code":"EUR","in_stock":true},{"title":"5 mg \/ 6+ pieces","offer_id":56145626104140,"sku":"2NLX.3","price":331.93,"currency_code":"EUR","in_stock":true},{"title":"5 mg \/ 24+ pieces","offer_id":56145626136908,"sku":"2NLX.3","price":314.46,"currency_code":"EUR","in_stock":true},{"title":"10 mg \/ 1 piece","offer_id":56145626169676,"sku":"2NLX.4","price":607.4,"currency_code":"EUR","in_stock":true},{"title":"10 mg \/ 6+ pieces","offer_id":56145626202444,"sku":"2NLX.4","price":577.03,"currency_code":"EUR","in_stock":true},{"title":"10 mg \/ 24+ pieces","offer_id":56145626235212,"sku":"2NLX.4","price":546.66,"currency_code":"EUR","in_stock":true},{"title":"25 mg \/ 1 piece","offer_id":56145626267980,"sku":"2NLX.5","price":865.4,"currency_code":"EUR","in_stock":true},{"title":"25 mg \/ 6+ pieces","offer_id":56145626300748,"sku":"2NLX.5","price":822.13,"currency_code":"EUR","in_stock":true},{"title":"25 mg \/ 24+ pieces","offer_id":56145626333516,"sku":"2NLX.5","price":778.86,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2NLX-SF_c8a3621f-fdef-4fcc-b249-e6d51fb35f19.jpg?v=1766418668","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/l-phenylalanine-13c-sub-6-sub-2nlx-2nlx","provider":"Luminix Health","version":"1.0","type":"link"}
