The occurrence of (2E,4E)-5-Hydroxy-2,4-pentadienal Potassium Salt 40418-44-8 Potassium Glutaconate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2E,4E)-5-Hydroxy-2,4-pentadienal Potassium Salt 40418-44-8 Potassium Glutaconate (CAS 40418-44-8) is a high-purity analytical reference standard with the molecular formula C5H5O2K and a molecular weight of 136.19 g/mol.
Structurally, (2E,4E)-5-Hydroxy-2,4-pentadienal Potassium Salt 40418-44-8 Potassium Glutaconate (C5H5O2K) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 136.19 g/mol, it falls into the low-molecular-weight range. 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).
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.
