With a molar mass of 138,1 g\/mol, The compound serves as a useful intermediate and reference material in studies of branched-chain amino-acid metabolism, organic synthesis and analytical chemistry. Its well-defined molecular composition supports precise weighing, solution preparation and documentation within experimental workflows. Supplied by manufacturer Carl ROTH, this sodium salt fits standard chemical and life-science laboratory practice. quantity provides enough material for multiple assays, method optimisation or small-scale preparative work without excessive surplus. Researchers value such characterised keto-acid derivatives for pathway investigations, enzyme assays and building-block chemistry. Clear CAS and formula data help maintain traceability from receipt through to final experimental records, making the product a practical choice for laboratories requiring reliable biochemical reagents.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-nl\/collections\/metals-elements-and-oxides\"\u003eMetals, elements \u0026amp; oxides\u003c\/a\u003e, in \u003ca href=\"\/en-nl\/collections\/inorganic-chemicals\"\u003eInorganic chemicals\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAssay (titr.): ≥ 98 %\u003c\/li\u003e\n\u003cli\u003eColour: white to light 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: 3715-29-5\u003c\/li\u003e\n\u003cli\u003ePack sizes: 25 g, 50 g, 100 g, 250 g\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₅H₇NaO₃\u003c\/li\u003e\n\u003cli\u003eMolar mass: 138,1 g\/mol\u003c\/li\u003e\n\u003cli\u003eStorage temperature: +2 to +8 °C\u003c\/li\u003e\n\u003cli\u003eWeight: 0,043 kg\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2X2K-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMzQyNXxhcHBsaWNhdGlvbi9wZGZ8YURSbEwyZzVaUzg1TWpVME56WXpNREF6T1RNMEwxTlFSVnBmTWxneVMxOUZUaTV3WkdZfGEwOTA3OGY4MTc2OTFmM2VmODQ3MWFmZjE5MjRmODgzNDBiNjYyNGU0MWZjNjAwNzAyMzNmYTViMzVhNGU2Mjc\" 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-2X2K-DE-DE.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3w3ODY1MHxhcHBsaWNhdGlvbi9wZGZ8YURJMkwyZzBPUzg1TVRrMk1qazJNekEyTnpFNEwxTkVRbDh5V0RKTFgwUkZYMFJGTG5Ca1pnfDFkZjE1NzM3NjExMzJhZjhkMDRkMDQxMTQzYjg0MTgyNDhkZjU2YWJkZTJiNmE5M2U1ZTkzOGNlYjI0ODUxOWQ\" 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 g \/ 1 piece","offer_id":56147886899532,"sku":"2X2K.1","price":557.95,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 6+ pieces","offer_id":56147886932300,"sku":"2X2K.1","price":530.05,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 24+ pieces","offer_id":56147886965068,"sku":"2X2K.1","price":502.16,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 1 piece","offer_id":56147886997836,"sku":"2X2K.2","price":826.7,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 6+ pieces","offer_id":56147887030604,"sku":"2X2K.2","price":785.37,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 24+ pieces","offer_id":56147887063372,"sku":"2X2K.2","price":744.03,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 1 piece","offer_id":56147887096140,"sku":"2X2K.3","price":1235.2,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 6+ pieces","offer_id":56147887128908,"sku":"2X2K.3","price":1173.44,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 24+ pieces","offer_id":56147887161676,"sku":"2X2K.3","price":1111.68,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 1 piece","offer_id":56147887194444,"sku":"2X2K.4","price":2234.95,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 6+ pieces","offer_id":56147887227212,"sku":"2X2K.4","price":2123.2,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 24+ pieces","offer_id":56147887259980,"sku":"2X2K.4","price":2011.46,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2X2K-SF_5b0723e6-04c4-42dd-8937-bf1151b62bfe.jpg?v=1766419613","url":"https:\/\/www.luminixhealth.com\/en-nl\/products\/sodium-3-methyl-2-oxobutanoate-2x2k-2x2k","provider":"Luminix Health","version":"1.0","type":"link"}
