Answer:It is used to prepare reference or calibration solutions for measurements of 2-oxoglutaric acid in analytical samples. Applicable workflows include validated GC-MS and LC-based metabolite assays.
Answer:The package contains 10 mg of neat α-ketoglutaric acid analytical standard. This size is suitable for preparing small quantities of calibration stock where extensive bulk reagent is unnecessary.
Answer:Keep the material at 2–8°C and observe the lot expiry date. Analytical standards require controlled preparation and documentation to maintain traceability of calibration concentrations.
Supelco α-ketoglutaric acid analytical standard provides neat 2-oxoglutaric acid for preparing calibration solutions, method controls, and reference preparations in analytical chemistry. α-Ketoglutaric acid is a tricarboxylic acid-cycle intermediate with molecular formula C5H6O5, CAS number 328-50-7, and molecular weight 146.10 g/mol. The small 10 mg package is useful for investigations requiring limited standard quantities, such as urinary and plasma metabolite profiling or chromatographic assay development. Analytical methods include gas chromatography–mass spectrometry and liquid chromatography with UV or tandem mass spectrometric detection after method-specific sample preparation. The material has an assay specification of 99.0–101.0% by titration and is supplied as an analytical standard rather than a general synthesis reagent. Store at 2–8°C and respect the lot expiry date because the standard has a limited shelf life. Prepare concentration calculations from the exact weighed mass and any documented assay correction required by the method.
