α-Ketoglutaric acid disodium dihydrate, min. 95 %, 500 g

α-Ketoglutaric acid disodium dihydrate is a biochemical salt offered at a minimum purity of 95 % for laboratory research. It carries CAS number 1282616-74-3, the empirical formula C₅H₄Na₂O₅(H₂O)₂ and a molar mass of 226,09 g/mol. The disodium dihydrate form provides a defined α-ketoglutarate source for aqueous solution preparation, metabolic studies and analytical work that require known composition and stoichiometry. Stated purity and hydrate formula support reproducible stock solutions and molar calculations. The product is available from manufacturer Carl ROTH in the biochemicals category and integrates into experimental designs that specify a characterised α-ketoglutaric acid salt. Accurate molar-mass data simplify weighing for target molarities, while the generous unit quantity helps maintain continuity across multi-day protocols. Groups working in biochemistry, cell-metabolism research and organic salt applications can rely on CAS-linked identity together with the min. 95 % specification for documentation. This presentation balances research-oriented definition with practical bulk packaging for routine and scale-up laboratory use.
