rac Geosmin D3

About rac Geosmin D3

rac Geosmin D3 is a stable isotope labelled standard carrying the CAS registry number 135441-88-2. Formula C12H22O, molecular weight 185.32 g/mol. Its systematic (IUPAC) name is (4S,4aS,8aR)-4-methyl-8a-(trideuteriomethyl)-1,2,3,4,5,6,7,8-octahydronaphthalen-4a-ol.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. Good laboratory practice and suitable PPE are recommended during handling.

Its mass shift relative to the unlabelled analyte makes it a dependable internal standard for LC-MS/MS assays, improving accuracy in bioanalysis, therapeutic drug monitoring and method validation. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

Available in 10 mg, 25 mg, 50 mg and 100 mg packs, rac Geosmin D3 is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
