{"product_id":"mpeg-sub-7-sub-sh-2px5-2px5","title":"mPEG7-SH, 100 mg","description":"\u003cp\u003emPEG7-SH is a thiol-terminated monodisperse methoxy polyethylene glycol reagent identified by CAS number 651042-82-9 and the empirical formula C₁₅H₃₂O₇S. It has a molar mass of 356,48 g\/mol and a density of 1,065 g\/cm³. Additional thermal data include a flash point of 210 °C and a boiling point of 423,7 °C, which assist safe handling assessments and process documentation. The material is Clear reporting of formula, molar mass, density, and thermal properties enables accurate dosing and identity confirmation against internal methods. Sourced from manufacturer Carl ROTH for chemical and biochemical use, mPEG7-SH is described strictly according to the stated molecular and physical parameters, giving laboratories a compact, well-defined PEG-thiol building block for research-scale applications.\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\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eColour: colorless to light yellow\u003c\/li\u003e\n\u003cli\u003eForm: liquid\u003c\/li\u003e\n\u003cli\u003e¹H-NMR Spectrum: corresponds to assigned structure\u003c\/li\u003e\n\u003cli\u003ePurity (NMR): ≥ 95 %\u003c\/li\u003e\n\u003cli\u003eCAS number: 651042-82-9\u003c\/li\u003e\n\u003cli\u003ePack sizes: 100 mg, 250 mg, 500 mg, 1 g\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₁₅H₃₂O₇S\u003c\/li\u003e\n\u003cli\u003eMolar mass: 356,48 g\/mol\u003c\/li\u003e\n\u003cli\u003eDensity: 1,065 g\/cm³\u003c\/li\u003e\n\u003cli\u003eFlash point: 210 °C\u003c\/li\u003e\n\u003cli\u003eBoiling point: 423,7 °C\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2PX5-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMzAyMHxhcHBsaWNhdGlvbi9wZGZ8YUdSaEwyaGhNeTg1TWpVME56UTFORFF3TWpnMkwxTlFSVnBmTWxCWU5WOUZUaTV3WkdZfGI3M2UwNDFjZWIwMmZkZjFmOGEyNTgxMmU0MWU0YmNmYjk5Y2FlYmE0YTUyNGVmZmE0ZDdjMWYyZjM0ZGEyYWU\" 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-2PX5-DE-DE.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3w3ODY1MHxhcHBsaWNhdGlvbi9wZGZ8YURrMkwyZzFPQzg1TVRrMk1qWXlOVEl5T1RFd0wxTkVRbDh5VUZnMVgwUkZYMFJGTG5Ca1pnfGY2MDRjMWU3NDdjYjQ4YjhmYjU1ZDZlZmM3NmZlZmRlMmZiMmE4ZmIyM2JiOTZhYzU3YWJmNDg3NDI2NDY2NGE\" 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":"100 mg \/ 1 piece","offer_id":56146215403852,"sku":"2PX5.2","price":203.2,"currency_code":"EUR","in_stock":true},{"title":"100 mg \/ 6+ pieces","offer_id":56146215436620,"sku":"2PX5.2","price":193.04,"currency_code":"EUR","in_stock":true},{"title":"100 mg \/ 24+ pieces","offer_id":56146215469388,"sku":"2PX5.2","price":182.88,"currency_code":"EUR","in_stock":true},{"title":"250 mg \/ 1 piece","offer_id":56146215502156,"sku":"2PX5.3","price":353.7,"currency_code":"EUR","in_stock":true},{"title":"250 mg \/ 6+ pieces","offer_id":56146215534924,"sku":"2PX5.3","price":336.02,"currency_code":"EUR","in_stock":true},{"title":"250 mg \/ 24+ pieces","offer_id":56146215567692,"sku":"2PX5.3","price":318.33,"currency_code":"EUR","in_stock":true},{"title":"500 mg \/ 1 piece","offer_id":56146215600460,"sku":"2PX5.4","price":600.95,"currency_code":"EUR","in_stock":true},{"title":"500 mg \/ 6+ pieces","offer_id":56146215633228,"sku":"2PX5.4","price":570.9,"currency_code":"EUR","in_stock":true},{"title":"500 mg \/ 24+ pieces","offer_id":56146215665996,"sku":"2PX5.4","price":540.86,"currency_code":"EUR","in_stock":true},{"title":"1 g \/ 1 piece","offer_id":56146215698764,"sku":"2PX5.5","price":998.7,"currency_code":"EUR","in_stock":true},{"title":"1 g \/ 6+ pieces","offer_id":56146215731532,"sku":"2PX5.5","price":948.77,"currency_code":"EUR","in_stock":true},{"title":"1 g \/ 24+ pieces","offer_id":56146215764300,"sku":"2PX5.5","price":898.83,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2PX5-SF_9d9a88fa-9f5f-451b-af20-6dd75f796fde.jpg?v=1766419153","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/mpeg-sub-7-sub-sh-2px5-2px5","provider":"Luminix Health","version":"1.0","type":"link"}
