Chemical Structure
Description
The occurrence of Sodium (Z)-4-(1-ethyl-5-methyl-1H-pyrazol-4-yl)-1,1-difluoro-4-oxobut-2-en-2-olate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Sodium (Z)-4-(1-ethyl-5-methyl-1H-pyrazol-4-yl)-1,1-difluoro-4-oxobut-2-en-2-olate (CAS 1197240-25-7), a certified reference material (molecular formula C10H11F2N2O2Na, MW 252.20 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H11F2N2O2Na, Sodium (Z)-4-(1-ethyl-5-methyl-1H-pyrazol-4-yl)-1,1-difluoro-4-oxobut-2-en-2-olate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 252.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), Sodium (Z)-4-(1-ethyl-5-methyl-1H-pyrazol-4-yl)-1,1-difluoro-4-oxobut-2-en-2-olate 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.
