As a certified reference material (CRM), Sodium (Z)-1,1,1-trifluoro-4-(5-methylthiophen-2-yl)-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.
Sodium (Z)-1,1,1-trifluoro-4-(5-methylthiophen-2-yl)-4-oxobut-2-en-2-olate (CAS 1197240-17-7) is a high-purity analytical reference standard with the molecular formula C9H6F3O2SNa and a molecular weight of 258.19 g/mol.
The molecular framework of Sodium (Z)-1,1,1-trifluoro-4-(5-methylthiophen-2-yl)-4-oxobut-2-en-2-olate (C9H6F3O2SNa) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
