It is identified by CAS number 1823122-52-6, has the empirical formula C₂₀H₃₁N₅O₁₀C₂HF₃O₂HPF₆ and a molar mass of 761,48 g\/mol. The NHS ester functionality enables covalent coupling to primary amines, introducing a DOTA-type chelator motif that is widely used when subsequent metal complexation is required in imaging, radiopharmaceutical or analytical method development. Offered as the hexafluorophosphate and trifluoroacetate compound from manufacturer Carl ROTH, this preparation is intended for chemical and biochemical laboratories that need a defined activated DOTA building block. It fits conjugation workflow optimisation, small-scale synthesis and exploratory labelling studies where precise stoichiometry and a compact pack size are advantageous.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAssay: reported\u003c\/li\u003e\n\u003cli\u003eColour: white to off-white\u003c\/li\u003e\n\u003cli\u003eForm: powder\u003c\/li\u003e\n\u003cli\u003econtent (HPLC-MS): ≥ 90 %\u003c\/li\u003e\n\u003cli\u003eCAS number: 1823122-52-6\u003c\/li\u003e\n\u003cli\u003ePack sizes: 25 mg, 50 mg, 100 mg\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₂₀H₃₁N₅O₁₀C₂HF₃O₂HPF₆\u003c\/li\u003e\n\u003cli\u003eMolar mass: 761,48 g\/mol\u003c\/li\u003e\n\u003cli\u003eProduct form: hexafluorophosphate, 2,2,2-trifluoroacetate compound\u003c\/li\u003e\n\u003cli\u003eApplication area: bioconjugation and chelator introduction\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2K3Y-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwNDEzM3xhcHBsaWNhdGlvbi9wZGZ8YUdNeEwyZ3dNaTg1TWpVME5EWXpOalk0TWpVMEwxTlFSVnBmTWtzeldWOUZUaTV3WkdZfDc0NWU1ZTI4NTlhY2YwMjVkM2EyZGUwNjk1ZWZkMDBiMjliMTA2NTNkNWYzZWQwM2VkZDA1OTg4ZDdmNzc4NmQ\" 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-2K3Y-DE-DE.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3w3ODY1MHxhcHBsaWNhdGlvbi9wZGZ8YUdObUwyZzFOeTg1TVRrMk1UWXdORFV3TlRrd0wxTkVRbDh5U3pOWlgwUkZYMFJGTG5Ca1pnfDcwNDA4NDViZTQzN2ZkZmFmMTdjOTc4MDhjNDZhM2IwNDY4ZGNjNjNjZDM0YmI4NzNkYmY0OTdiMGFmZDUyMmY\" 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":"25 mg \/ 1 piece","offer_id":56137222324556,"sku":"2K3Y.3","price":338.65,"currency_code":"EUR","in_stock":true},{"title":"25 mg \/ 6+ pieces","offer_id":56137222357324,"sku":"2K3Y.3","price":321.72,"currency_code":"EUR","in_stock":true},{"title":"25 mg \/ 24+ pieces","offer_id":56137222390092,"sku":"2K3Y.3","price":304.79,"currency_code":"EUR","in_stock":true},{"title":"50 mg \/ 1 piece","offer_id":56137222422860,"sku":"2K3Y.4","price":514.95,"currency_code":"EUR","in_stock":true},{"title":"50 mg \/ 6+ pieces","offer_id":56137222455628,"sku":"2K3Y.4","price":489.2,"currency_code":"EUR","in_stock":true},{"title":"50 mg \/ 24+ pieces","offer_id":56137222488396,"sku":"2K3Y.4","price":463.46,"currency_code":"EUR","in_stock":true},{"title":"100 mg \/ 1 piece","offer_id":56137222521164,"sku":"2K3Y.5","price":790.15,"currency_code":"EUR","in_stock":true},{"title":"100 mg \/ 6+ pieces","offer_id":56137222553932,"sku":"2K3Y.5","price":750.64,"currency_code":"EUR","in_stock":true},{"title":"100 mg \/ 24+ pieces","offer_id":56137222586700,"sku":"2K3Y.5","price":711.14,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2K3Y-SF_e72e8353-da35-4964-ada2-a3238ff3eecc.jpg?v=1766417709","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/dota-nhs-ester-compound-with-hexafluorop-2k3y-2k3y","provider":"Luminix Health","version":"1.0","type":"link"}
