Compared with other compounds in its class, the molecular weight of 156.22 g/mol gives Potassium acetylacetonate hemihydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Potassium acetylacetonate hemihydrate (CAS 57402-46-7), molecular formula C5H7O2KH2O and molecular weight 156.22 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Potassium acetylacetonate hemihydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 156.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
