Chemical Structure
Description
α-Keto Isovaleric Acid-13C,d Sodium SaltDISCONTINUED (C4[13C]H6DO3 Na) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
α-Keto Isovaleric Acid-13C,d Sodium SaltDISCONTINUED (CAS 1329835-35-9) is a high-purity analytical reference standard with the molecular formula C4[13C]H6DO3 Na and a molecular weight of 139.10 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), α-Keto Isovaleric Acid-13C,d Sodium SaltDISCONTINUED meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
