{"product_id":"colistin-sodium-methanesulfonate-29ey-29ey","title":"Colistin sodium methanesulfonate, 500 mg","description":"\u003cp\u003eColistin sodium methanesulfonate is a polymyxin-derived biochemical reagent provided as the sodium methanesulfonate salt for laboratory research. It carries CAS number 8068-28-8 and the empirical formula C₅₈H₁₁₅N₁₆Na₅O₂₈S₅, with a molar mass of 1759,9 g\/mol. This defined salt form is used in microbiological and pharmaceutical studies that require a characterised colistin derivative for experimental work. The product is Identity and molar-mass data follow the manufacturer description from Carl ROTH, supporting reproducible weighing and solution preparation. Colistin sodium methanesulfonate is applied in antimicrobial research, susceptibility testing workflows and related life-science applications where a polymyxin methanesulfonate salt is specified. Documented CAS, formula and pack information help laboratories maintain clear records, transfer methods between sites and manage inventory of specialised biochemical reagents used in bacterial and pharmaceutical research programmes.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/inorganic-salts\"\u003eInorganic salts\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/collections\/inorganic-chemicals\"\u003eInorganic chemicals\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eColour: white to light yellow or cream\u003c\/li\u003e\n\u003cli\u003eForm: powder to crystalline powder\u003c\/li\u003e\n\u003cli\u003eLoss on drying: ≤6 %\u003c\/li\u003e\n\u003cli\u003eAssay: batch-specific value\u003c\/li\u003e\n\u003cli\u003e¹H-NMR Spectrum: complies\u003c\/li\u003e\n\u003cli\u003eCAS number: 8068-28-8\u003c\/li\u003e\n\u003cli\u003ePack sizes: 500 mg, 2 g, 10 g, 25 g\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₅₈H₁₁₅N₁₆Na₅O₂₈S₅\u003c\/li\u003e\n\u003cli\u003eMolar mass: 1759,9 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-29EY-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMzI2MHxhcHBsaWNhdGlvbi9wZGZ8YUdSaUwyaGxZUzg1TWpVME5qTTJOREl4TVRVd0wxTlFSVnBmTWpsRldWOUZUaTV3WkdZfGM1ZjllMzc4ZGM4ZDQ3MThiYWY5ZWU3NDRhZWMxNDNkZWNjMDdjMzg0ODA1OGEyZDhjMTc5MDlkMDdmOTg4OWM\" 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-29EY-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyMzk4MTZ8YXBwbGljYXRpb24vcGRmfGFEQXdMMmcxWlM4NU1qQTJORFU1TkRrNE5USTJMMU5FUWw4eU9VVlpYMFJGWDBWT0xuQmtaZ3xlMGFkODMwYzhkMDhkNzdlZDg0YmVlMjEwZmY2YzNiZjU1MDU0MjQxZjI5MDI5MzdiM2U2YTljY2NmOTQ3MGQy\" 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":"500 mg \/ 1 piece","offer_id":56131118104908,"sku":"29EY.2","price":181.7,"currency_code":"EUR","in_stock":true},{"title":"500 mg \/ 6+ pieces","offer_id":56131118137676,"sku":"29EY.2","price":172.62,"currency_code":"EUR","in_stock":true},{"title":"500 mg \/ 24+ pieces","offer_id":56131118170444,"sku":"29EY.2","price":163.53,"currency_code":"EUR","in_stock":true},{"title":"2 g \/ 1 piece","offer_id":56131118203212,"sku":"29EY.3","price":568.7,"currency_code":"EUR","in_stock":true},{"title":"2 g \/ 6+ pieces","offer_id":56131118235980,"sku":"29EY.3","price":540.27,"currency_code":"EUR","in_stock":true},{"title":"2 g \/ 24+ pieces","offer_id":56131118268748,"sku":"29EY.3","price":511.83,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 1 piece","offer_id":56131118301516,"sku":"29EY.4","price":2492.95,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 6+ pieces","offer_id":56131118334284,"sku":"29EY.4","price":2368.3,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 24+ pieces","offer_id":56131118367052,"sku":"29EY.4","price":2243.66,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 1 piece","offer_id":56131118399820,"sku":"29EY.5","price":3320.7,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 6+ pieces","offer_id":56131118432588,"sku":"29EY.5","price":3154.67,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 24+ pieces","offer_id":56131118465356,"sku":"29EY.5","price":2988.63,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-29EY-SF_c82f8658-fec1-43e6-b602-94f592b5f7ef.jpg?v=1766415429","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/colistin-sodium-methanesulfonate-29ey-29ey","provider":"Luminix Health","version":"1.0","type":"link"}
