{"product_id":"c-methylcalix-4-resorcinarene-2p4h-2p4h","title":"C-Methylcalix[4]-resorcinarene, 1 g","description":"\u003cp\u003eC-Methylcalix[4]-resorcinarene is a resorcinarene macrocycle with CAS number 65338-98-9 and the empirical formula C₃₂H₃₂O₈. Its molar mass is 544,59 g\/mol, reflecting a tetrameric phenolic scaffold used in host–guest chemistry and supramolecular research. The product is The C-methyl-substituted calix[4]resorcinarene framework offers a preorganised cavity and multiple phenolic sites for further functionalisation or assembly. Clear molecular formula and mass data support accurate preparation of stock solutions and stoichiometric complexation experiments. Material from manufacturer Carl ROTH is intended for chemical and biochemical laboratory applications where defined macrocyclic building blocks are required. Researchers apply such resorcinarenes in molecular recognition, sensor development, and the construction of extended supramolecular architectures. The small pack supports economical evaluation while preserving material for characterisation and follow-up reactions under standard laboratory documentation practices.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/organic-building-blocks-and-synthesis-reagents\"\u003eOrganic building blocks \u0026amp; synthesis reagents\u003c\/a\u003e, in \u003ca href=\"\/en-be\/collections\/organic-chemicals-and-synthesis-reagents\"\u003eOrganic chemicals \u0026amp; synthesis reagents\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePurity (HPLC): ≥ 95 %\u003c\/li\u003e\n\u003cli\u003eColour: white to dark beige to faint orange to orange\u003c\/li\u003e\n\u003cli\u003eForm: powder to crystalline powder\u003c\/li\u003e\n\u003cli\u003e¹H-NMR Spectrum: corresponds to assigned structure\u003c\/li\u003e\n\u003cli\u003eCAS number: 65338-98-9\u003c\/li\u003e\n\u003cli\u003ePack sizes: 1 g, 2 g, 5 g, 10 g\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₃₂H₃₂O₈\u003c\/li\u003e\n\u003cli\u003eMolar mass: 544,59 g\/mol\u003c\/li\u003e\n\u003cli\u003eStorage temperature: +2 to +8 °C\u003c\/li\u003e\n\u003cli\u003eWeight: 0,002 kg\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2P4H-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMzAzNnxhcHBsaWNhdGlvbi9wZGZ8YUdWakwyZ3hZUzg1TWpVME56TTFPVE0zTlRZMkwxTlFSVnBmTWxBMFNGOUZUaTV3WkdZfDQ0MzFkY2Q1OGY5Mzc2MTMxMzAzMDg2OWU2ZjExY2M0OWI4ZmVhOTE2M2RjOWFlYTNkNmMxMTM0NTNkMmU0MGU\" 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-2P4H-DE-DE.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3w3ODY1MHxhcHBsaWNhdGlvbi9wZGZ8YUdZd0wyZ3dOQzg1TVRrMk1qUXlORFk0T0RrMEwxTkVRbDh5VURSSVgwUkZYMFJGTG5Ca1pnfDg1YjNlZTY1OWMyOTQ5OWJkNTk5ZmE2NWQ3OWRkNzFhZGVlYTA1OWQ2YmI1ZTI3NTA1ZjEwNWRlY2JhZDU1OGQ\" 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":"1 g \/ 1 piece","offer_id":56145698881868,"sku":"2P4H.2","price":241.9,"currency_code":"EUR","in_stock":true},{"title":"1 g \/ 6+ pieces","offer_id":56145698914636,"sku":"2P4H.2","price":241.9,"currency_code":"EUR","in_stock":true},{"title":"1 g \/ 24+ pieces","offer_id":56145698947404,"sku":"2P4H.2","price":241.9,"currency_code":"EUR","in_stock":true},{"title":"2 g \/ 1 piece","offer_id":56145698980172,"sku":"2P4H.3","price":446.15,"currency_code":"EUR","in_stock":true},{"title":"2 g \/ 6+ pieces","offer_id":56145699012940,"sku":"2P4H.3","price":423.84,"currency_code":"EUR","in_stock":true},{"title":"2 g \/ 24+ pieces","offer_id":56145699045708,"sku":"2P4H.3","price":401.54,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 1 piece","offer_id":56145699078476,"sku":"2P4H.4","price":1020.2,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 6+ pieces","offer_id":56145699111244,"sku":"2P4H.4","price":969.19,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 24+ pieces","offer_id":56145699144012,"sku":"2P4H.4","price":918.18,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 1 piece","offer_id":56145699176780,"sku":"2P4H.5","price":1961.9,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 6+ pieces","offer_id":56145699209548,"sku":"2P4H.5","price":1863.81,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 24+ pieces","offer_id":56145699242316,"sku":"2P4H.5","price":1765.71,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2P4H-SF_3e9ee49c-15c6-4a3d-95a3-95ecb86f9729.jpg?v=1766418788","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/c-methylcalix-4-resorcinarene-2p4h-2p4h","provider":"Luminix Health","version":"1.0","type":"link"}
