Chemical Structure

4-Hydroxy-2-oxovaleric Acid Potassium Salt CAS 3318-73-8 chemical structure

Description

The occurrence of 4-Hydroxy-2-oxovaleric Acid Potassium Salt is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Hydroxy-2-oxovaleric Acid Potassium Salt (CAS 3318-73-8) is a high-purity analytical reference standard with the molecular formula C5H8O4 and a molecular weight of 132.11 g/mol.

The molecular framework of 4-Hydroxy-2-oxovaleric Acid Potassium Salt (C5H8O4) is characterized by a carbohydrate-derived structure. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.

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.
