Chemical Structure
Description
CATO supplies alpha-Ketoglutaric acid-[13C2,d2] (CAS 123953-28-6), a certified reference material (molecular formula C3[13C]2H4D2O5, MW 150.10 g/mol) for analytical method development and quality control.
Owing to deuterium isotope labeling, a carbohydrate-derived structure, alpha-Ketoglutaric acid-[13C2,d2] is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 150.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
