Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 252.19 g/mol gives Sodium (Z)-4-(1-ethyl-3-methyl-1H-pyrazol-4-yl)-1,1-difluoro-4-oxobut-2-en-2-olate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Sodium (Z)-4-(1-ethyl-3-methyl-1H-pyrazol-4-yl)-1,1-difluoro-4-oxobut-2-en-2-olate (CAS 1332317-69-7) is a high-purity analytical reference standard with the molecular formula C10H11F2N2NaO2 and a molecular weight of 252.19 g/mol.
The molecular framework of Sodium (Z)-4-(1-ethyl-3-methyl-1H-pyrazol-4-yl)-1,1-difluoro-4-oxobut-2-en-2-olate (C10H11F2N2NaO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
